repository: retrieve worktree HEAD via refdb The function `git_repository_head_for_worktree` currently uses `git_reference__read_head` to directly read a given worktree's HEAD from the filesystem. This is broken in case the repository uses a different refdb implementation than the filesystem-based one, so let's instead open the worktree as a real repository and use `git_reference_lookup`. This also fixes the case where the worktree's HEAD is not a symref, but a detached HEAD, which would have resulted in an error previously.
