getItemPosition (and possibly indexOf, etc) returning wrong index for WeekMode

#285 #291

Reproducible by creating a RV of MCVs, setting them to Week mode, and scrolling them off screen to trigger CalendarPagerAdapter#getItemPosition and calling setMinimumDate(today) during onBind. As of 05/10/2016, on creation the calendar shows week of 05/04 - 05/10, but scroll through and it will rebind as 04/27 - 05/03. This is because month mode would have shown minDate as 04/27 (which is correct) but week mode has no intelligent way of setting a narrower minDate at the moment.

Seems like the issue is coming from materialCalendarView#setFirstDayOfWeek(Calendar.WEDNESDAY);
