Bug 16200: Convert all existing expired holds accounttype to HE

Before Bug 16200 expired holds have used accounttype F which is also used by
other type of fines. This patch updates all existing expired holds to new
accounttype HE (Hold Expired).

To test:
-1. Make sure you translated the string in previous patch of this buug
1. Find a Patron with "Hold waiting too long" fines and go to his Fines tab
2. Change Koha's language to some other than English
3. Observe that "Hold waiting too long" is still in English
4. Apply patch and run database update
5. Go back to Patron's Fines tab
6. Observe that "Hold waiting too long" is now translated
