RemoveEvent in multi-user view.

[tobiascapin]

When an event touchs multiple users and I call removeEvent() just the first event in dom is removed.
The solution is very simple: remove the "return false" in each loop at row 399:

      self.element.find('.wc-cal-event').each(function() {
        if ($(this).data('calEvent').id === eventId) {
            $(this).remove();
            //  return false; <-- remove this
        }
      });
