Fix intermittent failures in DistributedDataStoreRemotingIntegrationTest

testTransactionRetryWithInitialAskTimeoutExOnCreateTx has failed a couple
times on jenkins. After leader shutdown it times out trying to elect a
new leader. This is b/c the time outs set are small for the test and it
sometimes runs quick enough before member-3 has actually joined the
cluster. So I added calls to wait for members to join the cluster before
running the test.
