refdb: create references in commondir
References for a repository are usually created inside of its gitdir.
When using worktrees, though, these references are not to be created
inside the worktree gitdir, but instead inside the gitdir of its parent
repository, which is the commondir. Like this, branches will still be
available after the worktree itself has been deleted.
The filesystem refdb currently still creates new references inside of
the gitdir. Fix this and have it create references in commondir.
