I've since moved tests that aren't protocol-related into qmp-cmd-test.

As discussed in review of v1, test_object_add_without_props() isn't
protocol-related.  It tests a bug in qmp_object_add() we fixed in commit
e64c75a975.  Sadly, we don't have systematic object-add tests.  This
lone test can go into qmp-cmd-test for want of a better home.

test_qom_set_without_value() isn't about qom-set, it's about a bug in
infrastructure used by the QMP core, fixed in commit c489780203.  We
covered the bug in infrastructure unit tests (commit bce3035a44).  If we
want to test it at the QMP level as well, the test could go into
qmp-test.  Do we want to?

In my quick rebase, I added both tests to qmp-cmd-test.c out of
laziness.
