/**
 * Tests that a secondary can successfully apply an applyOps command that was created with an inner
 * "ts" field specified. If the primary receives such a command, it should apply it in non-atomic
 * mode since that is an over-specified applyOps oplog entry.
 *
 * This is a regression test for SERVER-44938.
