Make ResultView controls always visible

For many use cases the test runner NetBeans ui ResultView is more user friendly
than the maven output. However it is not enabled by default, and most annoyingly,
the button to set the view to show always is visible only after you have been able to get the
window to show a test result at all. The button I am talking about is indicated with an arrow in the picture below.

So therefor it would be nice to always enable the button bar at the left hand side.
A refresh button would be a nice addition, which should simply re-read the unit test report files.
