HHH-15473 Don't confuse property initialization for collection initialization in tests

Browse Source 
Checking for property initialization was acceptable and pretty
much the only way to perform assertions before we fixed HHH-14620,
but now that initializing a property doesn't imply initializing
the collection, it's just plain wrong:

* If you expect the collection *not* to be initialized, then
  checking that that the property is not initialized is too strict:
  the assertion could fail because the property is initialized
  while the collection is not initialized.
* If you expect the collection to be initialized, then
  checking that that the property is initialized is not enough:
  the assertion could pass because the property is initialized
  while the collection is not initialized.

Besides, we can safely call the getter to test the collection
directly with Hibernate.isInitialized(entity.getCollection())
since a call to the getter is not supposed to trigger collection
initialization.
