[I] Deadlock of TEST_F(ShellTestSuite, quitTest) (celix)

   This issue has been with us for a very long time, though recently it seldom reproduces.
   https://github.com/apache/celix/commit/b706d163543f403921498b5250244e561ad04298 has fixed a framework reference leak, which could lead to deadlock when shutting down a framework instance.
   
   However, this issue is still not fixed, since its root cause is very special:
   calling `celix_bundleContext_stopBundle`/`celix_framework_stopBundleAsync` via `celix_bundleContext_useServiceWithOptions` on the framework instance to be stopped.  
   
   The culprit is the last `celix_framework_fireGenericEvent` in `celix_bundleContext_useServiceWithOptions`, which may leak an event carrying  a reference to the framework instance, which has no chance to be processed (the event loop has already been stopped).
   
   Note that calling `celix_bundleContext_stopBundle`/`celix_framework_stopBundleAsync` via `celix_bundleContext_useServiceWithOptions` on a **normal**(non-framework) bundle is OK. Because `celix_bundleActivator_stop` of that bundle will synchronize with `framework_shutdown`. That said, there is nothing to worry about using `quit`/`stop` command via TUI or within any other normal bundle.
