MR Widget Subheader feels duplicative when there is only one Test Suite
Summary
When there is only one test suite to display in the merge request widget, the subheader is almost exactly the same as the widget title, so not offering any really added value.

Possible fixes
Very simply, we could hide the subheader if there isn't more than one test suite to display data from. Alternatively, we could consider the entire subheader structure and come up with something that takes less space to reproduce largely the same copy. As the size of the MR page grows in both size and concern, this might be a good time to cut down on vertical space if we can. How much we want to do here is likely up to UX
