GDBusProxy: report an error instead of leaking it

Browse Source 
GDBusProxy sets an error on a GSimpleAsyncResult and then returns
without dispatching the result for completion (and leaks the result in
the process).  Fix that.

Also add a testcase.  Unfortunately, adding the testcase uncovered
bug #672248.  We can work around that by reordering the tests.
