Bug 30045: (bug 29543 follow-up) Fix SCO print slip

Certainly since bug 29543 and bug 29914.

We should do the same authentication check than sco-main.pl, and also
make sure to generate the checkout history only for the logged in patron
(the OPAC one, not staff member)

Test plan:
Use the different combinations of the SCO config (AutoSelfCheckAllowed,
SelfCheckoutByLogin and WebBasedSelfCheck) and confirm that this patch
fixes the SCO print slip feature.
