Subject: [PATCH] test: Produce useful output when the HTML with images test
	fails

Previously, this would simply indicate that the grep failed without
any indication of the Emacs output it failed on.  Now we take
advantage of the test framework's handling of stdout to display the
incorrect Emacs output if the test fails.

Besides being a good idea in general, this is the first step toward
fixing this test on the Notmuch buildbot, since right now there's no
indication of why it's failing.
