ivi-shell: Remove all surface transitions when it is being removed. 

If surface transitions are not removed when surface is being removed, it
can lead to crash later when transition will finish, as it will try to
reference already freed memory.
This change exposes function that can remove all existing transitions
for given surface and it is being called during surface cleanup.
