Ensure CI detects failing tests

There is currently a bug in the `ts-jest` project [1] which causes
compile failures to result in a masked failing exit code *if test
coverage is being generated*.

The best solution would be to patch upstream, but in lieu of that we are
going to just run tests twice: once without coverage and once with
coverage.

Issue #457 npm run test:ci prints failures but exits success
