Fix T38295: Crash when changing screen with different visible layers

The issue was caused by missing object update for the curve object
before going to new screen. And that new screen had different visible
layers due to disabled lock_camera_and_layers option.

Solved by calling DAG_on_visible_update() in ED_screen_set() even
in cases scene doesn't change. This ensures all the objects which
weren't visible before are correctly updated.
