[QA] ResourceLoader versus Chrome browser

[Chris McMahon]

For some time tests run in Sauce Labs have been failing in Chrome because
calls to ResourceLoader cause errors.  I have been trying to reproduce
these manually, and I have seen it once or twice, and I think Rummana has
also, but we don't have a consistent reproduction.  If you see a page fail
to load in Chrome on any wiki in the system, please let us know.

For the sake of completeness, here are some of the errors in Chrome seen
overnight:
