Bug 36421: Make sure pre-controller errors are correctly logged

Bug 36421: Make sure pre-controller errors are correctly logged

If something explodes in Koha::REST::V1::Auth chances are that no logging will happen.

This patch makes sure they are!

To test:
1. Make sure you do NOT have 36420 on your tree
2. Make sure you are looking at the logs:
   $ ktd --shell
  k$ koha-plack --restart kohadev; tail -f /var/log/koha/kohadev/*.log
3. Use Postman or similar for hitting some known endpoint. Use
   the user's cardnumber instead of the userid. On a default KTD launch, the
   generated user's cardnumber is '42'.
   GET /patrons
=> FAIL: You get a 500 error (expected, fixed on 36420) but no useful logging found.
4. Apply this patch
5. Ctrl+c on the logs and re-run the command
6. Repeat 3
=> SUCCESS: You get a 500, but you also get the exception information logged!
7. Sign off :-D
