      const randomCollName = "randColl"
assert.commandWorked(db.runCommand({create: randomCollName}));
const randomCollUUID = db.getCollectionInfos({name: randomCollName})[0].info.uuid;


const tsViewName = "tsViewNs";
db.createCollection(tsViewName, {timeseries: {timeField: "t", metaField: "m"}});
assert.commandWorked(db.runCommand({drop: tsViewName, collectionUUID: randomCollUUID}));

      If the above is stored as myrepro.js, the results differ pending on whether the environment is sharded or not. 

      It returns "expectedCollection: <buckets collection name>" when run on a replica set.

      dropCollection() on a timeseries view namespace with a mismatched collectionUUID returns CollectionUUIDMismatch.

      However, when run on a replica set, we get "'expectedCollection': <timeseries buckets namespace>". When run through the mongos, we get "'expectedCollection': <timeseries view ns>".
