SerializationUtilsTest identity assertions

Replaced calls to assertTrue with a != condition with calls to
assertNotSame calls.
This change retains the functionality, but will produce a more
detailed error message in case the assertion fails.
It also (arguably) makes the test code more straight-forward.
