added method to reset the global JaMoPP class path
Modified test to make sure that test method execution order does matter.
As of JUnit 4.11 the execution order of the test methods does no longer
match the order in the source file (see
https://github.com/junit-team/junit/blob/master/doc/ReleaseNotes4.11.md).
To make sure that the meta test methods are executed last, the new
annotation @FixMethodOrder is used.
