[ABS] close share-panel after forward app.

Patch fixes behavioral change intruduced in
3d5b45c60e66e44f9aee2701e64ec84bc723ad0b. When share-panel
use aul_forward_app it should exit instead of waiting
for paused state.
Patch fixes display bug (share-panel blink after app was
selected).
Additionally remove all clean-up functions from terminate_cb
since the seems useless.
