grab: gracefully handle the case when we try to grab parent of wdir
Before this patch, we go all the way down to obsmarker creation logic and gets
an error saying that changeset cannot obsolete itself. We should be more smart
here and error out early saying we cannot grab that changeset.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once
$ hg init test1
$ cd test1
$ mkcommits _a _b
$ hg up "desc(_a)"
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit bdivergent1
