t5516: test pushing a tag of an otherwise unreferenced blob

Browse Source 
It's not unreasonable to have a tag that points to a blob
that is not part of the normal history. We do this in
git.git to distribute gpg keys. However, we never explicitly
checked in our test suite that this actually works (i.e.,
that pack-objects actually sends the blob because of the tag
mentioning it).

It does in fact work fine, but a recent patch under
discussion broke this, and the test suite didn't notice.
Let's make the test suite more complete.
