Modify to work with new drools-pdp

Due to sonar fixes, drools-pdp changed in a way that requires changes
to drools-applications.  In the case of template.demo, lots of test cases
had to be modified, so they were refactored to extract common setup and
tear down code.
Fixed checkstyle issues.
Fixed license date.
