Running `tools/wpt.ts` with a filter would cause an error if there were extra, leftover expectations in expectations.json. These errors would not appear if no filter was passed, often leaving the filtered version of the test runner broken. This also introduces a smarter bit of logic where filters can be specified with a leading slash (`tools/wpt.ts run -- /url` is equivalent to `tools/wpt.ts run -- url`)
