topic: check for devel.randomseed existence correctly

Judging by the block of code above this patch, we want to check for presence of
the same config option as we then add. So in this case, it would be
devel.randomseed, and not just devel.random. I couldn't find any mention of
devel.random in evolve, topic or core, which makes me think it was just a typo.

Checking target ambiguity in hg next

  $ hg init ambiguous-next
  $ cd ambiguous-next

  $ mkcommit root
  $ hg topic A
  marked working directory as topic: A
  $ mkcommit A1
  active topic 'A' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit A2
  $ mkcommit A3
  $ mkcommit A4
  $ hg up 'desc("A3")'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit A5
  $ hg up 'desc("A2")'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg topic B
  $ mkcommit B1
  active topic 'B' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit B2

  $ hg log -G
  @  7 [B] B2

  o  6 [B] B1

  | o  5 [A] A5

Quick sanity check

  $ hg up 'desc("A1")'
  switching to topic A
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [s2] A2
  $ hg stack
  ### topic: A (2 heads)
  ### target: default (branch)
  s5: A4
  s3^ A3 (base)
  s4: A5
  s3: A3
  s2@ A2 (current)
  s1: A1
  s0^ root (base)
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [s3] A3
  $ hg log -G
  o  7 [B] B2
  |
  o  6 [B] B1
  |
  | o  5 [A] A5
  | |
  | | o  4 [A] A4
  | |/
  | @  3 [A] A3
  |/
  o  2 [A] A2
  |
  o  1 [A] A1
  |
  o  0 [] root
  
  $ hg next
  ambiguous next changeset:
  [s5] A4
  [s4] A5
  explicitly update to one of them
  [1]

Let's make some changesets unstable

  $ hg up 'desc("A2")'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo foo > A2
  $ hg amend
  5 new orphan changesets
  $ hg stack
  ### topic: A (2 heads)
  ### target: default (branch)
  s5$ A4 (orphan)
  s3^ A3 (base orphan)
  s4$ A5 (orphan)
  s3$ A3 (orphan)
  s2@ A2 (current)
  s1: A1
  s0^ root (base)
  $ hg log -G
  @  8 [A] A2
  |
  | *  7 [B] B2
  | |
  | *  6 [B] B1
  | |
  | | *  5 [A] A5
  | | |
  | | | *  4 [A] A4
  | | |/
  | | *  3 [A] A3
  | |/
  | x  2 [A] A2
  |/
  o  1 [A] A1
  |
  o  0 [] root
  

Simply walking on unstable changesets should work as expected

  $ hg up 'desc("B2")'
  switching to topic B
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg prev
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [s1] B1
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [s2] B2

B1 shouldn't be considered a target, orphan or not

  $ hg up 'desc("A2")'
  switching to topic A
  1 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg next
  move:[s3] A3
  atop:[s2] A2
  working directory is now at 2b67b6a6cae1

B1 is not considered a target when it's been stabilized

  $ hg up 'desc("A2")'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg evolve --rev 'desc("B1")'
  move:[6] B1
  atop:[8] A2
  switching to topic A
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [s3] A3

A4 and A5 should be ambiguous for hg next even if A5 is an orphan and A4 is not

  $ hg evolve --rev 'desc("A3") + desc("A4")'
  move:[s5] A4
  atop:[s3] A3
  $ hg up 'desc("A3")'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg stack
  ### topic: A (2 heads)
  ### target: default (branch)
  s5: A4
  s3^ A3 (base current)
  s4$ A5 (orphan)
  s3@ A3 (current)
  s2: A2
  s1: A1
  s0^ root (base)
  $ hg next --no-evolve --dry-run
  hg update 51d70e81d730;
  [s5] A4
  $ hg next
  ambiguous next changeset:
  [s5] A4
  [s4] A5
  explicitly update to one of them
  [1]

  $ cd ..

Making sure plain hg next sticks to topic when target is unstable

  $ hg init next-unstable-topic
  $ cd next-unstable-topic

  $ mkcommit ROOT
  $ hg topics topic-a
  marked working directory as topic: topic-a
  $ mkcommit A
  active topic 'topic-a' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg topics topic-b
  $ mkcommit B
  active topic 'topic-b' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg up 'topic("topic-a")'
  switching to topic topic-a
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo foo > foo
  $ hg ci -A --amend
  adding foo
  1 new orphan changesets
  $ hg log -G
  @  3 [topic-a] A
  |
  | *  2 [topic-b] B
  | |
  | x  1 [topic-a] A
  |/
  o  0 [] ROOT
  

  $ hg next
  no children on topic "topic-a"
  do you want --no-topic
  [1]

  $ hg next --no-topic
  move:[2] B
  atop:[3] A
  working directory is now at 53f8332d648f

  $ cd ..
