evolve: stop preserving all of {extras} for uninterrupted evolve operations

I doubt the wisdom of doing this, but the case of completing interrupted evolves
does this, as do core commands for amend, graft, and rebase in hg ce9696193175,
bb14a81ce647, and b698abf971e7.

Note the obslog order (and DAG display) change in test-evolve-content-divergent-relocation.t
around line 131.  I have no idea why that would happen, or if it's an indicator
of something subtle going on.

Setup
=====

  $ . "$TESTDIR/testlib/topic_setup.sh"

  $ hg init test-list
  $ cd test-list
  $ cat <<EOF >> .hg/hgrc
  > [phases]
  > publish=false
  > EOF
  $ cat <<EOF >> $HGRCPATH
  > [experimental]
  > # turn evolution on
  > evolution=all
  > EOF

  $ mkcommit() {
  >    echo "$1" > "$1"
  >    hg add "$1"
  >    hg ci -m "add $1"
  > }

Build some basic graph
----------------------

  $ for x in base_a base_b base_c base_d base_e ; do
  >   mkcommit $x
  > done

Add another branch with two heads

  $ hg up 'desc(base_a)'
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg branch lake
  marked working directory as branch lake
  (branches are permanent and global, did you want a bookmark?)
  $ mkcommit lake_a
  $ mkcommit lake_b
  $ hg up 'desc(lake_a)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit lake_c
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')


Add some topics
---------------

A simple topic that need rebasing

  $ hg up 'desc(base_c)'
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg topic baz
  marked working directory as topic: baz
  $ mkcommit baz_a
  active topic 'baz' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit baz_b

A simple topic with instability

  $ hg up 'desc(base_d)'
  1 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg topic fuz
  marked working directory as topic: fuz
  $ mkcommit fuz_a
  active topic 'fuz' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit fuz_b
  $ mkcommit fuz_c
  $ hg up 'desc(fuz_a)'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg commit --amend --message 'fuz1_a'
  2 new orphan changesets

A topic with multiple heads

  $ hg up 'desc(base_e)'
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg topic bar
  marked working directory as topic: bar
  $ mkcommit bar_a
  active topic 'bar' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit bar_b
  $ mkcommit bar_c
  $ hg up 'desc(bar_b)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit bar_d
  $ mkcommit bar_e
  $ hg up 'desc(bar_d)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg commit --amend --message 'bar1_d'
  1 new orphan changesets

topic 'foo' on the multi headed branch

  $ hg up 'desc(lake_a)'
  1 files updated, 0 files merged, 7 files removed, 0 files unresolved
  $ hg topic foo
  marked working directory as topic: foo
  $ mkcommit foo_a
  active topic 'foo' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit foo_b

Actual Testing
==============

basic output

  $ hg topic
     bar (5 changesets, 1 unstable, 2 heads)
     baz (2 changesets)
   * foo (2 changesets)
     fuz (3 changesets, 2 unstable)

quiet version

  $ hg topic --quiet
  bar
  baz
  foo
  fuz

verbose

  $ hg topic --verbose
     bar (on branch: default, 5 changesets, 1 unstable, 2 heads)
     baz (on branch: default, 2 changesets, 2 behind)
   * foo (on branch: lake, 2 changesets, ambiguous destination: branch 'lake' has 2 heads)
