Bug 17403: Internal Server Error while deleting patron

This patch fixes a Internal Server Error while deleting patrons.

To reproduce:

- Go to a patron's detail page
- Toolbar : More : Delete
- Confirm "Are you sure you want to delete..."

Result: Internal Server Error
Plack error log:
exited nonzero: 1 at /home/marc/koha/members/deletemem.pl
Note: Patron is deleted

Additional tests: Try to delete yourself, to delete a staff member
without having superlibrarian permission etc.

To test:

- Apply patch
- Re-start plack
- Try to reproduce steps above (with other patron)
Expected result:
No Internal Server Error, Redirect to Home > Patrons

Amended to include all occurences of 'exit 1'
