evolve: use merge.update() for resolving phase divergence
Iterating over the manifest when tree manifests and narrowness is in
play produces entries for paths outside the narrowspec that represent
trees. For example, if the tests/ directory of the hg repo was not in
the narrowspec (and the hg repo was using tree manifests, which it
doesn't), then there would be a "tests/" entry in the manifest. The
merge code deals with some of these cases. For example, it's valid to
do a merge if only the local side changes directories outside the
narrowspec. That allows rebasing a local commit onto a public commit
that had changes to the excluded paths to work.
However, _resolvephasedivergent() was iterating of the manifests,
which resulted in crashes for some of our users when they tried to
resolve phase-divergent commits (actually content-divergent commits
that became phase-divergent after the intermediate rebase). We can fix
that by relying on merge.update(), since that already handles this
case.
