  submodule: resolve URLs relative to main worktree It is possible to specify submodule URLs relative to the repository location. E.g. having a submodule with URL "../submodule" will look for the submodule at "repo/../submodule". With the introduction of worktrees, though, we cannot simply resolve the URL relative to the repository location itself. If the repository for which a URL is to be resolved is a working tree, we have to resolve the URL relative to the parent's repository path. Otherwise, the URL would change depending on where the working tree is located. Fix this by special-casing when we have a working tree while getting the URL base.
