epriestley 02c3200867 Respond more gracefully when a git push deletes a nonexistent ref
Summary:
Fixes T5534. If you `git push origin :refs/tags/doesnotexist` (for some non-existing tag), we get a change where both the old and new refs are empty.

We incorrectly call this an "add", because the old ref is empty. Instead, call this a "delete", but skip the logic which would normally mark it dangerous.

(Possibly we should just reject these outright, but Git allows them, so stick with that for now.)

Test Plan:
Pushed nonexistent refs:

```
  $ git push origin :refs/tags/doesnotexist
  remote: warning: Allowing deletion of corrupt ref.
  To ssh://dweller@localhost/diffusion/POEMS/
   - [deleted]         doesnotexist
  $
```
