update: fix bare --clean to work on new branch (issue5003) (BC)

Before this commit bare update --clean on newly created branch
updates to the parent commit, even if there are later commits
on the parent commit's branch. Update to the latest head on the
parent commit's branch instead.

This seems reasonable as clean should discard uncommited changes,
branch is one of them.
