    window: Fix issues with opening files
    
    Baobab doesn't expect that file handler doesn't have to exists for certain
    mime type and consequently fails when opening file with "g_app_info_launch:
    assertion 'G_IS_APP_INFO (appinfo)' failed" critical in such case.
    
    It also requires only handlers which supports URIs. Consequently, for
    example, it is not possible to open folders in Thunar as it uses "%F" on
    its Exec line. But all supported URIs should be accessible over gvfsd-fuse
    mountpoint.
    
    Let's replace the whole logic to open files by simple
    g_app_info_launch_default_for_uri() to fix those issues.
