[FIXED JENKINS-29649] Now JUnit and TAP publisher do not clash with each other trying to draw plots on a project page

[anenviousguest]

TapTestResultAction was derived from hudson.tasks.test.TestResultProjectAction.TestResultAction

And hence this check was inherited too: https://github.com/jenkinsci/junit-plugin/blob/master/src/main/java/hudson/tasks/junit/TestResultAction.java#L96

With that said, when building a project page, JUnit's and TAP's test result actions were mutually exclusive to each other.

Hey @anenviousguest, excellent job! I'm checking out the project to build it. But thanks for the neat code, and for including tests! 👍

Tested locally the master branch. Created a job with JUnit and TAP. Confirmed the JUnit "Test Result" link in the sidebar is not displayed. No error messages in console.

Installed the .hpi file from this pull request. Opened the TAP action pages, no errors in console or web page. Still no JUnit Test Result link.

Re-executed the job, this time the plug-in correctly handled TAP and JUnit, and now I can see the TAP links in the sidebar, and also the JUnit action. No errors, all looking good. Changes merged, included in the next release. Thanks @anenviousguest !
