Bug 13122 - Patron holds table no longer display date item went in transit

In Koha 3.14 and earlier, an item on hold and in transit would display
the date the item was transferred. This is missing from the new ajax
holds table.

Test Plan:
1) Place an item on hold for delivery at a different library
2) Check the item in, confirm the hold and transfer
3) View the patron's holds tab on circulation.pl and/or moremember.pl
4) Note the item is show as in transit, but does not give the "since"
   date
5) Apply this patch
6) Note the in transit status now has a "since <date>"
