Remove red highlight for rows without tests on the test results page

[bkowshik]

Describe the bug

When some of the tests were deactivated and the tests were run, all rows were coloured Red in the test_status column.

To Reproduce

1. In the Tests menu item, deactivate all tests related to all_flight_data entity.

2. Next, run the tests for the project.

$ python3 ./run_everything.py --project_id 'ScanProject1'

Expected behavior

With all the tests active, we see that only rows with tests have the test_status coloured in Red.
