Fix T90630: Crash loading certain user preferences

Clearing the window was done in wm_file_read_post which was deferred.

This was needed as it left the context in an invalid state
where the window was set but the screen wasn't.

Crashing when setting up keymaps that attempted to access the
scene from the window in the property update function.
