Fixes #2649
When
allowInput
is true andallowInvalidPreload
is true and user enters some invalid value into input, Flatpickr throws an error and calendar UI is broken, because of that error. This happens because there is invalid value in self.selectedDates (set by setSelectedDate() function), but code that is executed further in setDate() function assumes that all values in self.selectedDates are always valid Date objects.This fix adds two simple checks to make sure we are dealing with Date objects before using Date methods.
