merge: consider successor changesets for a bare update

Previously, a bare update would ignore any successor changesets thus
potentially leaving you on an obsolete head. This happens commonly when there
is an old bookmark that hasn't been moved forward which is the motivating
reason for this patch series.

Now, we will check for successor changesets if two conditions hold: 1) we are
doing a bare update 2) *and* we are currently on an obsolete head.

If we are in this situation, then we calculate the branchtip of the successor
set and update to that changeset.

Tests coverage has been added.
