GEODE-10417: Fix NullPointerException in WAN replication (#7845)

* GEODE-10417: Fix NullPointerException in WAN replication

When the WAN group-transa$ction-events feature is enabled in
a parallel gateway sender, it is possible to get a NullPointerException
when retrieving events from the queue to complete a transaction if
the event in the queue is null.

If this situation is reached then the gateway sender dispatcher will
not dispatch queue events anymore and therefore the WAN replication
will not progress.

This happens because the predicates that check if elements
in the queue contain a transactionId are not protected
against the event being null.

A null check has been added before the predicates are invoked
so that in case of a null event, the predicate is not invoked
and the event is skipped from the checking.

* GEODE-10417: Change assertEquals to assertThat
