worktree: use fully qualified reference name for created HEAD

When creating a new worktree, we have to set up the initial data
structures. Next to others, this also includes the HEAD pseudo-ref.
We currently set it to the worktree respectively branch name, which is
actually not fully qualified.

Use the fully qualified branch name instead.
