Update object.php

Problem:
When you change an event from one calendar/agenda to an other calendar/agenda, it does not appear in the new calendar representation of the calendar app of owncloud.

We think we found the problem in calendar/lib/object.php

In the public static function moveToCalendar line 16 now is:
OC_Calendar_Calendar::touchCalendar($id);

This is probably incorrect because $id is the event-id and not the calendar-id in this function.

It seems to all work fine here when it is changed into:
OC_Calendar_Calendar::touchCalendar($calendarid);
