Bug 30266: Hide pickup location input on waiting hold

Bug 30266: Hide pickup location input on waiting hold

This patch updates the holds table to always insert a hidden input when a hold is 'found'
and covers the case where the hold is 'found' but doesn't match known statuses

To test:
 1 - Place two holds on a record for two different patrons, with different pickup locations
 2 - Check in one item at expected branch to set waiting
 3 - Then either:
    - Use batch modification or item editor to change the holding branch for the item
    - Sign in to a different branch and manually transfer the item back to it's home location
 4 - View the holds for the record
 5 - Note the 'Pickup library' column is blank for that hold
 6 - Change pickup location for other hold and press 'Update holds'
 7 - Note the waiting hold is still blank, and now second hold has no pickup location
 8 - Check the DB and note the first hold has had the pickup location changed
 8 - Apply patch
 9 - Delete holds and repeat 1-4
10 - Note the waiting hold now displays:
    Hold expected at {Branch}, please checkin to verify status
11 - Change location for second hold and update holds
12 - COnfirm location chanegd correctly and first hold unaffected
