[PATCH] test/emacs: revert invalid-from test to pre-86f89385 behaviour

[David Bremner <david@tethera.net>]

To the best of my understanding, this original behaviour was what
Carl's homebrew parser produced. With commit 86f89385 Austin switched
to using GMime (2.6). This produced arguably worse results, but since
the input was bad, we could live with it. Now with GMime 3.0 we are
getting the original results again, and there is no reason to consider
this test broken.
