evolve: strip the relocation commit on `hg evolve --stop`
While resolving content-divergence on multiple parents, we relocate one of the
commit on the parent of another one and then merge the divergent changesets.
Merging can leads to conflicts, and if user does `hg evolve --stop`, we need to
strip that relocated changeset too! This patch does that.
Test changes demonstrates the fix.
Tests for the --stop flag for `hg evolve` command while resolving phase-divergence
==================================================================================
The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on
This is testing cases when `hg evolve` command is doing phase-divergence resolution.
Setup

$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
$ hg init stoprepo
$ cd stoprepo
$ echo ".*\.orig" > .hgignore
$ hg add .hgignore
$ hg ci -m "added hgignore"
$ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;
