/**
* Since various migrations in BrowserGlue are sometimes trivial, e.g. just
* clearing a pref, it does not feel necessary to write tests for each of those.
*
* However, ensuring we have at least some coverage to check for errors, e.g.
* typos, is a good idea, hence this test.
*
* If your migration is more complex that clearing a couple of prefs, you
* should consider adding your own BrowserGlue migration test.
