As explained in ~~SERVER-46373~~ currently $lookup is not allowed to target a sharded collection in a multi document transaction due to 2 known reasons:

That a shard targeting itself will deadlock trying to re-acquire the same session
That if a different shard needs to be targeted, the shard does not know how to correctly start the multi-doc txn on that other shard.

After ~~SERVER-81190~~ unsharded collection will be tracked and $lookup as a consequence won't be allowed on a unsharded collection as well (within a transaction)

The goal of this ticket is to allow $lookup on an unsplittable collection if that collection is still on the primary. This is just a temporary fix before ~~SERVER-46373~~ to enable ~~SERVER-81190~~ to be merged and start tracking collections.
