Map reduce is versioned on direct connection to shards

After SERVER-48128 the requests sent directly to a shard should not be versioned, so, there shouldn't be any cache refresh on the node that a direct client can't retry, however, this is not the case, there is a cache refresh that's being called when executing a mapReduceWrite. Running a jstest will show that during the direct client check, there is a refresh while doing a mapReduceWithWrite.
