When, like in tst_QApplication::qtbug_103611(), a QApplication object is destroyed without calling exec(), then QDesktopUnixServices leaked its QDBusPendingCallWatcher, because the connection to the slot that would deleteLater() the watcher was disconnected, and the watcher had no QObject parent that would otherwise reap it. Fix by actually deleting the watcher in ~QDesktopUnixServices(), if it still exists (which implies disconnecting, of course). This makes tst_QApplication asan-clean on Linux/X11 (was: "75466 bytes leaked in 965 allocations"). Amends de609d84b9cee4a481d1718c00b09105d8c2ae69.
