Bug 24298: Record transfer triggers for returns

This patch adds handling to catch transfers that may have been triggered
on item return.

Test Plan:

1) Enable AutomaticItemReturn and accompanying system preference
2) Return an item to the wrong branch and note the transfer
3) Check the database for the new trigger value
