    proxy: Fix shadow mount handling for equal paths
    
    Automatic shadow mount handling in some cases works currently only thanks
    to the bug in g_daemon_file_prefix_matches implementation, which I am going
    to fix. The problematic case is when activation_root is equal to mount_root
    (e.g. Nextcloud integration). The bug in _prefix_matches causes that it
    succeeds also if the paths are equal, but this is wrong as per the docs.
    Let's use also g_file_equal when looking for shadow mounts in order to fix
    this issue.
