Add test counters information on test report page

Currently, the QA report app shows a summary of the reports in the main page as well as detailed reports in separate pages. However, while the summary in the main page shows detailed counters on the number of tests executed for a given image/build, the detailed report page only shows the number of test cases available for that image type and the detailed test counters information is missing.

The QA report is updated to have the same counters displayed in the main page and in the detailed report page for a given image/build, so that it is easy to verify the test counters from the test report page as well.
