Fix calendar system checks for pascha
Review Request #129667 - Created Dec. 18, 2016 and submitted - Latest diff uploaded
Date of pascha is currently computed wrongly. Commit b47ddff6 (switch from KCalendarSystem to QCalendarSystem) reversed all calendar system checks from equality to inequality in HolidayParserDriverPlan::pascha(), it seems to me by error (e.g. the first check is always true after the change). After reverting to equality checks, pascha date computation is correct.
