XPConnect generally throws when trying to create instances of non-DOM objects
in content. Due to some bugs this has historically worked in certain cases, but
we're fixing those now. So we need to fix the tests that do this sort of thing.
These are the manual fixes that the ensuing auto-generation can't deal with. Some of them
just fix up formatting (such as Components.\nFoo, so that subsequent auto-generation can
work better).
