Title: don't require the error message have the first line of HTTP output in it

HHVM doesn't match PHP on error message. The message we give is:

The "http://user:pass@www.example.com/something" file could not be downloaded: Failed to open http://user:pass@www.example.com/something ()

which seems reasonable. The test is already asserting it is 404 the line above.
