[PATCH 1/3] Make test "using invalid commit with -C" more strict

In the test 'using invalid commit with -C' git-commit would have failed
even if the -C option  had been given the correct commit, as there was
nothing to commit. Fix it by making sure there is always something to
commit and git-commit fails because of the invalid commit provided to
it.
