evolve: make sure user can recover from conflict (issue6053)
we make sure while continuing interrupted evolve it reach to right code
This patch fix the issue6053 which is about falling evolve into unrecoverable
state and this is how it call fall into it:
If after some rewrite operations we reach to a point where resparent for
two content divergent csets is obsolete and we hit a conflict in
relocation, so now if you run `hg evolve --continue` after resolving
the conflict: code execution would check if wdir parent is obsolete
and run solveobswdp() rather than going to continueevolve() part
and there we will hit by a "abort: outstanding uncommitted merge"
And same for `--abort` or `--stop` flags.
Changes in tests reflect the fixed behaviour.
This test file test the #5720 issue
Check that `hg evolve --continue` doesn't change changeset phase from secret
to draft after a merge conflict.

Test
====
$ hg init $TESTTMP/issue-5720
$ cd $TESTTMP/issue-5720
Create two drafts commits and one secret
$ echo a > a
$ hg commit -Am a
adding a
$ echo b > a
$ hg commit -m b
$ echo c > a
$ hg commit --secret -m c
$ hg log -G -T "{rev}: {phase}"
@ 2: secret

o 1: draft

o 0: draft
Amend the second draft with new content
$ hg prev
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
[1] b
$ echo b2 > a
$ hg amend
1 new orphan changesets
$ hg log -G -T "{rev}: {phase}"

Evolve which triggers a conflict
$ hg evolve
move:[2] c
atop:[3] b
merging a
warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
fix conflicts and see `hg help evolve.interrupted`
[1]
Fix the conflict
$ echo c2 > a
$ hg resolve -m
(no more unresolved files)
continue: hg evolve --continue
Continue the evolution
$ hg evolve --continue

Tip should stay in secret phase
$ hg log -G -T "{rev}: {phase}"
