Comment 7 for bug 1437103

I've pushed a branch here that should resolve the issue for the checkin UI: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/khuckins/lp1437103-suppress-popups-on-checkin

While the checkin UI's option was called "suppress_popups," the service was looking for "suppress_checkin_popups," but only on certain cases. I've expanded its reach a bit, and changed the references in the service to match the controller.

I also noticed that the option does not exist at all in the patron items out UI, where checkins can also be performed. Is this expected?
