26666	assertRedirects gives unhelpful error message expected URL is external	Peter Inglesby	Tobias McNulty	"`assertRedirects` uses the test client and so cannot fetch external URLs.  When the expected URL is set to an external URL, `assertRedirects` fails with something like:

{{{
AssertionError: 404 != 200 : Couldn't retrieve redirection page '/some-path/': response code was 404 (expected 200)
}}}

It would be better if `assertRedirects` could detect that it was being used incorrectly, and gave a more helpful error message."	Cleanup/optimization	closed	Testing framework	dev	Normal	fixed			Accepted	1	0	0	0	0	0
