#56 RBUTILS-055 (Task) Improve tests for RbGenerator (compile)

[redfish]

The problem in RBUTILS-016 (https://sourceforge.net/tracker2/?func=detail&aid=1812380&group_id=206198&atid=996695) with commons-lang as only be detected because we had the problem in the project build.
We should add integration tests with a properties file which contains data with weird keys and values AND compile the code produced by RbGenerator to track that kind of error.
