[FAB-4037] Fix intermittent timeouts in events UT

This CR resolves the issue leading to the intermittent UT failures
for the events package. It was caused by one test case setting the event
processor timeout to a low value without resetting the value at the end
of the test case.

This CR also removes fabric/events/events_test.go because its test cases
were all moved to fabric/events/producer_test.go by the CR that caused
the UT failures.
