Title: Explicitly remove ubuntugis-stable from Apt sources list.

Currently, the Travis-CI tests are breaking. Explicitly removing the reference to the `ubuntugis-stable` repository from Apt sources appears fix this problem. See: https://github.com/travis-ci/travis-ci/issues/2401

> We eventually tracked it down to the fact that the default build environment has both pgdg and ubuntugis-stable sources, and if you e.g. try and install python-gdal, this will uninstall the preinstalled postgresql-9.1-postgis-2.1 and libgdal1 (as that package is from pgdg and based upon GDAL 1.9) in order to install python-gdal and libgdal1h (from ubuntugis-stable and based upon GDAL 1.10).
