* Autocheckin test for order created through API
* Resolve migration conflict
We measured that this creates a ~10% performance loss on MySQL, but
believe that correctness is more important. Also, in case on concurrent
check-ins on MySQL with default transaction isolation level, this might
lead to Internal Server Errors on all but one check-ins, which is still
better than to show green.
* standardize use of check-in
* split on occurrence of "checkin_*"
Instead of skipping when encountering "checkin_*", we now split and only
pass the second part to the spell-checker. This fixes the aforementioned
problem.
