Runs AllTests on PHP 8 instead of PHP 7.4
@tsteur the tests are running now on PHP 8. But I needed to update to PHPUnit 9 for that build, as PHPUnit 8.5 doesn't support PHP 8. Unfortunately PHPUnit 9 doesn't support PHP < 7.3, so we can't update in general.
Nevertheless there seem a lot tests failing. Would need some time to investigate that a bit further. Let me know if or when I should plan to do that.
@sgiehl it seems to be mostly working? we could look into it as part of 4.1 if it's somewhat quick to do to fix these issues.
For now priority is 4.0.X and I think I pinged you on few other sec issues etc
@tsteur Actually might be a bit more. The second build that is shown as success actually silently fails. See https://travis-ci.com/github/matomo-org/matomo/jobs/455444024#L996
Not yet sure why the tests suddenly abort while running.
