Do not generate "hidden" field in oplog if collMod "hidden" parameter is a no-op

      collMod creates oplog entries, even when it does nothing. In FCV 4.2, it can create this oplog entry:

        {dbName: 'db10',commandObj: {collMod: 'coll12',index: {name: 'idx_f',hidden: false}}},

      It's not rejected since it's "hidden: false", but also 4.2 is unhappy due to this logic that expects an "expireAfterSeconds" field.
