Thiago Macieira fb16664893 Fix memory leaks with QDBusServer
Two serious mistakes:
 - we need to call dbus_server_free_data_slot as many times as we call
   dbus_server_allocate_data_slot
 - we need to delete the d pointer...

The changes to the unit tests are simply to cause the used peer
connections to be removed so they don't show up in valgrind.
