Automated test for issue 31

I added an automated test that reproduces https://github.com/TeamDewberry/jmxdatamart/issues/31

It's possible that I don't have all of the changes from TeamDewberry/master in my DavidWhitlock/master branch, but I'm pretty sure I've got everything.  And just to make sure that it's not my local environment at fault, I ran a buildhive build against this code:

https://buildhive.cloudbees.com/job/DavidWhitlock/job/jmxdatamart/63/console

The test failed as I expected.
