fix nullhandling exceptions related to test ordering (#9570)

* fix nullhandling exceptions related to test ordering

version and the test environment. This may lead to "NullHandling module
not initialized" errors for some tests where we do not initialize
null-handling explicitly.

* use InitializedNullHandlingTest
