2009281 Recent patrons duplication issues
Converts the user ID to a number to avoid duplicates caused
by type mismatches.
Removes duplicates before the ID is added or the array is
trimmed to avoid prematurely removing IDs.
To test:
1. Set "Number of Retrievable Recent Patrons" setting to 2
2. Open a patron record
3. Open a different patron record
4. Open Circulation->Retrieve Last Patron
5. Open Circulation->Retrieve Recent Patrons
Note: both patrons are present without duplicates
