test: adapt to change in cache warming in core

Core Mercurial has a more rational cache warming strategy now. 24f55686a63d
stopped warming of the cache after every changegroup application (in favor of
end of transaction warming).  This reflect in the blackbox test output.

Check that topic without any parent does not crash --list
---------------------------------------------------------

  $ hg up other
  switching to topic other
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg topic --list
  ### topic: other

Simple test

'hg stack' list all changeset in the topic

  $ hg topic

error case, nothing to list

  $ hg topic --clear
  $ hg stack
  abort: no active topic to list
  [255]

Test "t#" reference
-------------------


  $ hg up t2
  abort: cannot resolve "t2": no active topic
  [255]
  $ hg topic foo
  $ hg up t42
  abort: cannot resolve "t42": topic "foo" has only 4 changesets

  $ hg up t2

Case with some of the topic unstable

Also test the revset:

  $ hg log -r 'stack()'
  2 default {foo} draft c_c
  7 default {foo} draft c_d
  4 default {foo} draft c_e
  5 default {foo} draft c_f

Case with multiple heads on the topic
-------------------------------------

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
  rebasing 4:0f9ac936c87d "c_e"
  rebasing 5:6559e6d93aea "c_f"
  $ hg log -G
  o  9 default {foo} draft c_f

  o  8 default {foo} draft c_e

  |
  o  2 default {foo} draft c_c
  |
  o  1 default {} public c_b
  |
  o  0 default {} public c_a
  


Create the second branch

  $ hg up 'desc(c_d)'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo aaa > ggg
  $ hg add ggg
  $ hg commit -m c_g
  $ echo aaa > hhh
  $ hg add hhh
  $ hg commit -m c_h
  $ hg log -G
  @  11 default {foo} draft c_h
