Hello, thanks for this very excellent plug-in! One issue I noticed is that if I
have multiple kinds of test reports, say some JUnit and PHPUnit, and I enable
both JUnit and xUnit, I will get two identical test graphs on the job page, both
with the aggregated results. Of course, I only want one. This could be solved in
a few ways:

1. xUnit could check if JUnit is enabled also for this build, and not add the
graph if so.

2. xUnit could provide the ability to take JUnit results, which it wouldn't of
course need to transform, but then for this use case you wouldn't need to enable
two test reporting plugins.

Thanks again, looking forward to your thoughts.
