[PATCH v2] emacs: show: refresh buffer did not remove overlays

Previously refreshing the notmuch show buffer did not remove overlays
which meant that if the user refreshed a message with images the
images would remain and then the new text was added after.

One might have guessed that erase-buffer would have removed them but
it seems not.  Thus force the removal of overlays with remove-overlays.
---

This version fixes the problems that Austin mentioned in his review. I
have not investigated whether the erase-buffer here can be removed: it
looks like it could be but the worst that this does is call
erase-buffer twice (slightly wasteful but no harm).

Best wishes

Mark
