    settings: Tweak priorities for keyfile backend
    
    We want to use the keyfile backend in sandboxes,
    but we want to avoid people losing their existing
    settings that are stored in dconf. Flatpak does
    a migration from dconf to keyfile, but only if
    the app explictly requests it.
    
    From an app perspective, there are two steps to
    the dconf->keyfile migration:
    1. Request that flatpak do the migration, by adding
       the migrate-path key to the metadata
    2. Stop adding the 'dconf hole' to the sandbox
    
    To keep us from switching to the keyfile backend
    prematurely, look at whether the app has stopped
    requesting a 'dconf hole' in the sandbox.
