[TIMOB-14062] iOS Calendar: EventsAuthorizationResponse always return success in the first time even if the user press 'Don't Allow' button on the dialog requesting permission

EventsAuthorizationResponse always return success in the first time even if the user press 'Don't Allow' button on the dialog requesting permission. Here is the test case:

if(Ti.Calendar.eventsAuthorization == Ti.Calendar.AUTHORIZATION_AUTHORIZED) {
   // performCalendarReadFunctions();
 } else {
    Ti.Calendar.requestEventsAuthorization(function(e){
        if (e.success) {
           alert('You have granted access to the calendar');
            //performCalendarReadFunctions();
        } else {
            alert('Access to calendar is not allowed');
        }
    });

}

Scenarios which are tested are as follow: 1. First time authorization and user press 'Don't allow' button: We get 'Success' alert but still No calendar is shown. 2. After first authorization when 'Don't allow' was pressed : We get 'error' callback. 3. First time authorization and user press 'OK' button : We get 'Success' alert and calendar is shown.
