Subject: [PATCH] fix MC-252817 (green map markers do not disappear).
this bug is caused by the fact that the itemframe's item is set to empty before the green marker is requested to be removed. this is fixed by getting the mapid from this method's parameter, rather than the air block now stored by the item frame.
