GEODE-2213 Deadlock in GMSJoinLeaveJUnitTest
This removes the informToPendingJoinRequests invocation in recordViewRequest.
I was already testing this change as I suspected that this invocation was
causing new members to timeout trying to connect to the distributed system
due to informToPendingJoinRequests removing join requests from the view
creator's queue.
