In txn_two_phase_commit_write_concern.js, the test checks if the txn coordinator majority commits the decision irrespective of the user write concern. Due to PM-3489 it is no longer a valid assumption that a majority committed write has been applied on a majority of nodes yet, only that a majority have acknowledged it to be made durable in future. Before checking for majority committed decision here, we need to make sure that the writes are actually applied.
