[travis] rewire ctest calls

this builds and runs tests w/o ctest first. Errors here will and should
fail our travis build as such. Afterwards ctest is run again on a
cleaned build dir. This should replicate results and submit those to
cdash, while enabling us not to have the travis build fail due to ctest
itself failing.
