TestGameServerAllocationDuringMultipleAllocationClients: Readdress flake

The actual bug is here:
  https://github.com/googleforgames/agones/blob/2023077aff4125b9d9822c5d20cd773d13138385/test/e2e/gameserverallocation_test.go#L1423

When we tried to accept errors in googleforgames#3750, we forgot to
change this t.Errorf to a simple log.

Along the way, some cleanup.

Towards googleforgames#3553
