fix sourcehut brach/tag resolving regression 

nixos/nix#6290 introduced a regex pattern to account for tags when
resolving sourcehut refs. nixos/nix#4638 reafactored the code,
accidentally treating the pattern as a regular string, causing all
non-HEAD ref resolving to break.

This fixes the regression and adds more test cases to avoid future
breakage.
