Have CI coverage require other tests passing

[brettcannon]

There's no needs clause on coverage in PR CI, which means if the tests are definitely going to fail then they will fail twice: once for the normal test run and then again when run under coverage. Either coverage should be the way to run those tests so they aren't run twice or coverage should probably not run if the test suite failed.
