[PATCH 1/2] test: add emacs test for hiding message when point is at invisible text

[Dmitry Kurochkin]

Human-friendly scenario:

* open a thread which has at least 2 messages in notmuch-show view
* hide the first message
* move to the first line of the second message
* press C-a (bound to `beginning-of-visual-line')
* press RET (bound to `notmuch-show-toggle-message')

Result: the first message is shown
Expected result: the second message is hidden or shown

Currently the test is failing.  The bug will be fixed by a subsequent
patch.
