fix: change regex to support github.com:org/repo format as well as github.com/org/repo

Also add "fixed" status to display a "check"
fix(status-icons): seems there was a typo, added "no_tests" status

- Circle CI has another "Status" value when they don't have tests, "no_tests". Added that, set it to the same as unrecognised.
- Seems there was a typo, I assumed "icon-circle-slash" was meant by "icon-slash", as nothing appeared, so changed that.
