Fix Incorrect Times in TimePickerDialog

Bug 3414311

TimePicker#setCurrentHour subtracts 12 from the given hour if
is24HourView returns false. TimePickerDialog calls setCurrentHour before
setIs24HourView, so the 12 will always be substracted from the time.
Reorder the statements so that TimePickerDialog sets is24HourView,
before setting the hour and time.
