mvn builds running PDEunit tests in the integratation-test phase

This pull request  makes the build fail (see https://srv.elexis.info/jenkins/view/3.0/job/Elexis-3.0-Base-ngiger/lastBuild/testReport/) e.g. build 29

It should in my opinion howerver merged an the various problems should be fixed. E.g.
* atc-code refer missing files
* Several tests eg. loinc_test prompt the user to save resource patient/kontact, therefore never returning
*  Arzttarife tests work now, but asks for Elexis to restart

TODO on my side: externe_dokumente fails various tests.
