Dashboard doesn't handle outages very well

[simonwuelker]

There are currently no wpt runs happening for servo (servo/servo#37115) and the dashboard doesn't show any results anymore:

I would expect the line to cut off when there are no runs, similar to what happens with https://linegoup.lol

(servo is the purple line)

	const scores = FOCUS_AREAS.map(() => ({
	total_tests: 0,
	total_score: 0,
	total_subtests: 0,
	total_subtests_passed: 0
	}))
	for (const [test, { subtests }] of Object.entries(against_run.test_scores)) {

That's because the tests are taken from the last run.
