* Eliminate a class of errors where an inventory request could be made before the region had completely received the inventory for the user.

* A much larger race condition where the inventory request could be made before the region gets any data at all will also be fixed in the near future.
* This change also fixes a regression from two patches ago where items stopped appearing in standalone inventory
