During a $lookup pipeline construction we first attempt to build a pipeline using local information. If we fail to do so we assume we'll have to contact a remote shard.
Doing so ends up calling MultiStatementTransactionRequestsSender via CursorEstablisher.
However, in case we're inside a multi-document transaction we aren't releasing the checked out session on the originating shard. As a result, we'd end up deadlocking the operation if the collection exists on the originating shard again as they could end up contacting themselves and waiting for a checked out session.
