    gio-tool: Do not alter uris before use
    
    Uris may be altered by the following code, which breaks xdg-open:
    file = g_file_new_for_commandline_arg (arg[i])
    uri = g_file_get_uri (file);
    
    Examples of possible uri changes:
    mailto:email -> mailto:///email
    magnet:?xt=urn:hash -> magnet:///?xt=urn:hash
    ssh://user@host -> sftp://user@host
    
    This patch causes that uris aren't preprocessed for locations with
    scheme, however absolute and relative paths are still preprocessed.
