Bugfix: Only include ./bundled/setup_bundled.cmake

Remove a stray globbing expression that is not necessary any more and that

  $ cmake .

In this case ./bundled/cmake_install.cmake was accidentally picked up
leading to a file permission error if CMAKE_INSTALL_PREFIX was left at the
default /usr/local
use the fe index also in the case where triangulation was prepared for pure refinement

and add test that would fail without the patch and works fine now
