Bug 34901: Display transit status on patron holds tab only if hold found value is "T"

Bug 34901: Display transit status on patron holds tab only if hold found value is "T"

Check the transit status of the *hold* in addition to the transit status
of the *item*, to avoid displaying a misleading transit status on
item-level holds when the item is actually in transit for a different
hold

To test:
1. Create a record-level hold for Patron A for pickup at a library other
   than the logged-in library
2. Check in an item to fill that hold
3. Put an item-level hold on that same item for Patron B at a different
   library other than the logged-in library
4. Open Patron A's and Patron B's account details pages in separate tabs
--> Note that the Holds tab on Patron A's account detail page correctly
    shows that their hold is in-transit
--> Note that the Holds tab on Patron B's account detail page incorrectly
    shows that their hold on the same item is also in-transit
4. Apply patch
5. Clear browser cache
6. Refresh both patrons' account details pages
--> Confirm that the holds tab on Patron A's account still correctly
    says their hold is in-transit
--> Confirm that the holds tab on Patron B's account now correctly shows
    a blank status for their hold
7. Cancel Patron A's hold
8. Check in the item again to put it in transit for Patron B's hold
9. Reload Patron B's account page
--> Confirm that the holds tab on Patron B's account now correctly says
    their hold is in-transit
