The test checks that the coordinator has persisted that it is in either "committing" or "aborting" state before running collMod, createIndexes, and dropIndexes and asserting that these commands succeed. It should instead wait until donors/recipients are aware that the coordinator has persisted that it's in "committing"/"aborting" because we check whether collMod, createIndexes, and dropIndexes can succeed based on donors/recipients knowledge of the coordinator state.
