instead of adding that ForTesting method just for this test, can you keep things
all in chrome (since the receiver of this message is in chrome anyways). i.e.
you can get the TabContentsWrapper from browser()->GetSelectedWebContents() and
then call its translate_tab_helper() to get at the object that dispatches its
method. you'll have to make the BrowserMessageFilter methods on it public, but
that seems fine.
