[gjs] arg: Extract variable

[Philip Chimento <pchimento src gnome org>]

commit 951f7f79c01afc3a63ec26c2709caad267fe052d
Author: Philip Chimento <philip endlessm com>
Date:   Thu Sep 29 18:13:32 2016 -0700

    arg: Extract variable
    
    This is for readability and saves a few calls of val.toObject(). It will
    become convenient when we root the return value of toObject().
