Errors on "Classify Failures" tab if project is not selected

[tpapaioa]

If I do not have a project selected in the header dropdown in the ibutsu UI, then I can view all tabs of the test runs and individual test results, except for the run's Classify Failure tab. The page fails to load, and the browser console shows JS errors:

TypeError: t is null
    value filtertable.js:293
    value filtertable.js:301
[...]
    value run.js:378

If I select the correct project from the project dropdown, then the tab loads. I'm not sure why a project needs to be selected only for this one tab, but there should be some warning message if it's required, and it should display a helpful error message if there is a problem loading the results.

@tpapaioa great catch! I was able to reproduce it when doing patternfly 5 migration. We will deal with such issues later to provide better user experience!
