[PATCH weston 4/4] ivi-shell: fix the layer assignment change from one screen to another

[Emre Ucan]

if the layer is in order of some screen we need to remove it
from there and mark the screen order as dirty so it will be removed
in commit_screen_list call later
layer should only be assigned to one screen at a time
