Testing if the output "new commits" should appear in the long format of
"git status" was done by comparing the hashes of the diffpair. This always
resulted in printing "new commits" for submodules that contained untracked
or modified content, no matter if they also contained new commits. The
reason was that the two->sha1 is always the null_sha1 when diffing against
the work tree. This patch gets the correct ref to compare against by
calling resolve_gitlink_ref(.., "HEAD", ..).
Unfortunately the test case that should have found this bug had been
changed incorrectly too. It is fixed and extended to test for other
combinations too.

Another way to fix this bug would have been to enter the correct sha1
into two->sha1 for submodules with new commits. But i am not sure about
the side effects such a change would have and thus fixed it this way so
it could not hit anyone else.
