rollback: detect "parentgone" case earlier

Detecting this earlier will help us to affect the rollback process sooner, which
will help the next changesets.

To keep things simple, we degrade the behavior a bit when the `undo.desc` is
missing. However since `hg rollback` is not supposed to be used and the
`undo.desc` file have been introduced in mercurial 1.6 (2010). I think this is
an acceptable evil.
