[gnome-sound-recorder] gjs: Fix some "Too many arguments" warnings

[Jan Tojnar <jtojnar src gnome org>]

commit 8ae615d83b1b50b88f8977bfb9c03ce6ae396481

    gjs: Fix some "Too many arguments" warnings
    
    Removed some unnecessary parameters in certain functions.
    Due the recent GJS changes some parameters are not necessary,
    so make sense removing them for avoid some warning messages.
