push tests: add more testing for forced tag pushing 

Improve the tests added in dbfeddb12e ("push: require force for refs
under refs/tags/", 2012-11-29) to assert that the same behavior
applies various other combinations of command-line option and
refspecs.

Supplying either "+" in refspec or "--force" is sufficient to clobber
the reference. With --no-force we still pay attention to "+" in the
refspec, and vice-versa with clobbering kicking in if there's no "+"
in the refspec but "+" is given.

This is consistent with how refspecs work for branches, where either
"+" or "--force" will enable clobbering, with neither taking priority
over the other.
