NamespacesTest.testDeleteNamespaceWithBundles is flaky. It fails sporadically.

example failure

Sorry, I didn’t reproduce for local. I looked at the test code. It should be that the following code sequence is wrong.

Before delete a namespace, We should mock all done. 847 lines of code should be executed after 851 lines of code.

Otherwise, a null pointer may happen during verification isServiceUnitOwned
