You're stuck in something of a rut now. The way apt works is that it compares the installed versions of packages with the versions available in repositories, and updates if a higher version number is available to replace the existing installed version. Without reinstalling or manually downgrading each and every package from backports, you will just have to wait for the next Trisquel release to offer newer packages in the base release.
