Tests for issue #78.

* Made test order fixed in JUnit to exhibit problem with issue #78.
* Because there are side-effects from the order in which tests run, I've
made the order fixed. For running from within Eclipse this is fine, but
Maven required tweaking the config for tycho-surefire-plugin.
* It seems because the new test runner uses the Eclipse RCP there is no
need to manually load the RoboChart libraries from the class loader.
Again, this helps to show the problem for the new test.
