test for removing null listner
test for removing Phantom listner

test for removing valid listner and not getting an event after 5 seconds
refactored MembershipListenerTest

added test for adding null listener,
expected IllegalArumentException but was NullPointerException

so failing ?
still need to wait for the added member event
so using assertTrueDelayed5sec
All Test in MembershipListenerTest pass
