duplicate entries for "backup" files

[andcoz]

After editing some .desktop file in my quicklaunch dir, a lot of duplicate entries showed in the menu.

I discovered that quicklaunch was showing an entry not only for firefox.desktop file but also for firefox.desktop~ file, the backup file created by my editor of choice.

This simple patch solves the issue:

diff -crB QuickLaunch@github.com/extension.js QuickLaunch@github.com_fixed/extension.js

              let name = info.get_name();
!             if( name.indexOf('.desktop') > -1) {
                  let desktopPath =  GLib.build_filenamev([path, name]);
                  this._addAppItem(desktopPath);
                  i++;
