Fix heroku deployement for app names starting with "p" or later

[atomfrede]

When building a jar with maven we have two jars:

• xyz.jar (which is the exeutable jar) and
• original-xyz.jar

The procfile just started *.jar in case the app name was before o everything worked fine. In case the original jar was lexicographical before the executable jar it was tried to start that. In the main generator we don't have that problem as the original jar is named xyz.jar.original so we could just reference *.jar.

closes #126

e2e tests are failing because the selenium driver has a new version only compatible with a newer chrome version. I suspect the release will be published to the package repositories soon, so maybe just ignore the failing e2e tests for now
