/**
* Test that transaction operations wait for write concern (or don't) correctly on noop writes.
*
* We run most commands on a different connection. If the commands were run on the same
* connection, then the client last op for the noop writes would be set by the previous operation.
* By using a fresh connection the client last op begins as null. This test explicitly tests that
* write concern for noop writes works when the client last op has not already been set by a
* duplicate operation.
