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.
