Fix for UIDatePickerModeCountDownTimer callback
Fix for UIDatePickerModeCountDownTimer callback

If user taps “done” without picking a time, currently returns a
callback of 0 seconds though this is incorrect as the default selection
in the popup is 1 minute (note, user also can’t select 0 minutes).

Fixed so when date picker first instantiated, will set the selected
duration as 60 seconds
