evolve: update the public divergence resolution logic to cover --continue case
To continue the interrupted evolve in case of public divergence:
we will have to store the node of that public cset which was in
content divergence with the other cset, so that we can perform the
phase divergence resolution between that public cset and a newnode
which is the result of content-divergence resolution.
Added tests reflect the behaviour this patch adds.
Test for handling of content divergence with public cset using `hg evolve`
==========================================================================
Setup
=====
$ cat >> $HGRCPATH <<EOF
> [alias]
> glog = log -GT "{rev}:{node|short} {desc|firstline}\n {phase} {troubles}\n\n"
> [phases]
> publish = False
> [extensions]
> rebase =
> EOF
$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
Testing the case when both divergent cset are on the same parent and no-conflict in merging:
-------------------------------------------------------------------------------------
Prepare the repository:
$ hg init pubdiv
$ cd pubdiv
$ for ch in a b; do
> echo $ch > $ch;
> hg ci -Aqm "added "$ch;
> done;
$ hg glog
@ 1:5f6d8a4bf34a added b

Make an amend and change phase to public:
$ sed -i "1 i I am first" b
$ hg amend
$ hg phase --public
Amend again to create a cset divergent to public one:
$ hg up 1 --hidden -q
