Bug 1577180 - Get a profile before accessing BrowserGlue in test_getPotentialBreachesByLoginGUID.js. r=jaws

I'm not sure of the exact cause since that would require doing a local Windows beta build and the getService error doesn't indicate what failed inside the component. I mostly guessed that this was the problem by looking at other tests which do the same thing.
