TF runs with the same trigger

When listing the Testing Farm runs, as a user I would expect them to be grouped if they have the same trigger, i.e. set of tests triggered by multiple targets from a Copr build.

Example of a similar situation handled by Copr builds:

Instead of Status label here use an array of status labels similar to this.
We also need to remove the rightmost Test Results column because it’s different for each target.
