git-fetch test: test tracking fetch results, not just FETCH_HEAD

We really should have done this long time ago.  Existing t5515 test
was written for the specific purpose of catching regression to the
contents of generated FETCH_HEAD file, but it also is a good place
to make sure various fetch configurations do fetch what they intend
to fetch (and nothing else).
