comctl32/tests: Check for the outcome of the SendMessage calls in test_monthcal_size.

[Gerald Pfeifer]

Nikolay suggest that instead of dropping res here, it wouldn't hurt 
testing for the result of SendMessage.  So, that's what this patch does.

https://testbot.winehq.org/JobDetails.pl?Key=2055 is fine with it, too
(just W7PROX64 still running).
