Bug 32515: Ignore no-block flag in check-in message

Bug 12225 changed the templates to correctly pass through the no-block flag,
however, we don't have a no-block routine for checkins

This patch restore previous behaviour of performing a normal checkin when
no block was requested - it adds a new FIXME

To test:
1 - See bug 32537
    https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32537
2 - Repeat test plan on that bug, noting that there is no response when no-block = Y
3 - Apply this patch
4 - Repeat the tests and confirm no-block = Y has a standard checkin response
