Allow calling shadowed method when using addMethods.

[cancan101]

Currently this does not work:

pimcore.object.search.addMethods({
    onRowContextmenu: function ($super, grid, record, tr, rowIndex, e, eOpts) {
        if (pimcore.currentuser.admin === true) {
            $super(grid, record, tr, rowIndex, e, eOpts);
            return;
        }
        ///
     }
});

Since $super looks for a method on the superclass of pimcore.object.search and onRowContextmenu is defined on the class itself. With this PR, I can now do:

pimcore.object.search.addMethods({
    onRowContextmenu: function ($this, grid, record, tr, rowIndex, e, eOpts) {
        if (pimcore.currentuser.admin === true) {
            $this(grid, record, tr, rowIndex, e, eOpts);
            return;
        }
        ///
     }
});
