This patch makes the safe_to_delete method in Koha::Patron return this
new object type instead of a plain string. This way we have a consistent
way to deal with 'can_*'-like methods return values when feedback is
needed.
To test:
1. Apply this patch
2. Run:
$ kshell
k$ prove t/db_dependent/Koha/Patron.t
=> SUCCESS: The adjusted tests pass. Tests cover the boolean context
eval and also the carried messages, that include the same string code
that was returned originally.
3. Sign off :-D
