Revert "Exclude AggregatedTestResultPublisherTest"

https://github.com/jenkinsci/junit-plugin/releases/tag/1252.vfc2e5efa_294f
is the JUnit plugin release that fixes the test.

Special thanks to Tim Jacomb for fixing the test in
jenkinsci/junit-plugin#591

jenkinsci/junit-plugin#588 is the issue report
for the JUnit plugin tests that depend on the icon based build status
display.

jenkinsci/jenkins#8705 is the Jenkins core
pull request that switched from using icon based build status to symbol
based build status.  That change also fixes a layout issue in the Safari
web browser.

This reverts commit cb2376e.
