For the record, the ideal test factoring would probably have been to use a
TestExtensionDir from the C++ then manufacture the app, extension, and extension
iframe. This pattern of send XHR, wait for response, check there was response,
notify success is pretty common.

but no point rewriting things for that.

Good to know for the future. I'll keep the current CL as is though.
