Start DM will create a deadlock is user profile was never loaded

[BillCarsonFr]

With the new deferred DM flow when creating the local room entity, the current code will start a blocking write transaction:

        monarchy.awaitTransaction { realm ->
            createLocalRoomEntity(realm, roomId, createRoomBody)
            createLocalRoomSummaryEntity(realm, roomId, params, createRoomBody)
        }

and inside it createLocalRoomEntity will call DefaultCreateLocalRoomStateEventsTask
That itself will start a blocking write transaction via userService.resolveUser(it) that tries to store the profile in DB

  if (params.storeInDatabase) {
                // Insert into DB
                monarchy.writeAsync {
                    it.insertOrUpdate(UserEntityFactory.create(User.fromJson(params.userId, user)))
                }
            }
