Bug 38342: Pass the value to exception to avoid warnings

This patch makes the exception on bad enum values in Koha::Object->store
not print a warning in the event of stringifying the exception.

To test:
1. Run:
   $ ktd --shell
  k$ prove t/db_dependent/Koha/Booking.t
=> FAIL: You get this warnings:

```
Use of uninitialized value in sprintf at /kohadevbox/koha/Koha/Exceptions/Object.pm line 84.
```
2. Apply this patch
3. Repeat 1
=> SUCCESS: No more uninitialized values warnings
4. Sign off :-D
