From experience this test has uncovered a bunch of issues. Can we include
showBreakPoints in the test-api and migrate the related tests?

[jgruber, 2016/11/15 10:59:10]

Done. I've removed the parts using Debug.setBreakPointByScriptIdAndPosition -
let me know if you feel we should keep that as well.
