Subject: [PATCH] builtin/fetch: print hash of deleted tag when updating

`git fetch --tags` will unconditionally update (and thus overwrite)
existing tags, which is especially annoying for annotated and signed
tags.

Print the hash of the deleted tag so users can manually
recover their tags from such an update.
