tests: test that push doesn’t complain about unstable changesets if no changes When there’re no outgoing changes, push doesn’t complain about unstable changesets. There is currently a bug (see issue6372) that causes that there is an abort on push when the outgoing changes contain another changeset even if that is not obsolete or unstable. A test case and fix for that is sent in the next patch.
