gpui: Fix xdg_toplevel app_id set to None at first commit on Wayland (#55583)

This PR fixes the default behaviour of setting `app_id` to `None` which
breaks the rules based management by KWin as the first commit doesn't
have the actual `app_id` and apply initially setting stops checking for
the window by when it updates.

Closes #53962

Release Notes:

app_id at startup
