fixed unit tests refs #86

(FTE test is ignored at the moment)
fixed persistence xml
fixed unit tests for plato-model #86

* now tests can be run from command line,
* persistence.xml is excluded from generated jar
* and deployment from within eclipse does work

* it is not possible to run these junit tests from within eclipse, as
  the persistence.xml is then in the wrong path:
  m2e skips some maven lifecycle-phases it consideres as not important,
  and eclipse does not distinguish between normal build and test-build, so
  neither the persistence.xml can be copied to the right folder before tests,
  nor can it be removed from classes before deployment.

you have to add the error in plato-model/pom.xml to ignored errors
