Workaround to fix Heat stack deletion bug in Shade
There is a bug in Shade, in the function "event_utils.poll_for_events".
While Shade is waiting for the Heat stack to be deleted, retrieves
periodically the status of this Heat stack. When the stack is deleted,
the function "get_stack" [1] returns None; then L90 tries to access to
a key of this None object.
