Resume a pull whose rebase a lock error stopped partway through

If pull.rebase is set and a lock stops the rebase partway through, the
git command runner ran "git pull" again. This failed with "You are not
currently on a branch", and the rebase was left stopped halfway.

Handle this the same way as for an interactive rebase. Continue the
rebase if git rescheduled the todo that failed, give up if it didn't,
and run the pull again if the lock stopped it before the rebase
started.
