D5780: tags: avoid generating commit for an already deleted tag (issue5752)

[mharbison72 (Matt Harbison)]

  Since the tag command's code is already looking at `repo.tagtype()`, I wonder if it would be better to just inline the global tag lookup and nullid comparison right there instead of updating the interface.
