test: message: Remove incorrect slow receiver test

The slow receiver test verifies there's no race condition between
concurrent message delivery and object deletion. This is not a valid use
case in the first place, as objects are not allowed to be deleted from a
different thread than the one they are bound to. Remove the incorrect
test.
