Fix some crashes in chan_sip.  This patch changes various places that add
items
to the scheduler to ensure that they don't overwrite the ID of a
previously
scheduled item.  If there is one, it should be removed.
(closes issue http://bugs.digium.com/view.php?id=10391, closes issue
http://bugs.digium.com/view.php?id=10256, probably others, patch by me)
