After SERVER-38728, if we find a collection is unsharded, we will just perform a local read on it (with no shard versioning). We should change this to deal with cases where the collection becomes sharded. Depending on how we do the "is the collection sharded" check, this may also be needed to deal with the case where the collection exists (and is not sharded) but is on a different shard.
