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.

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = b"/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
# import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
