emacs: fix dangling overlays in notmuch-search

notmuch-search-insert-authors now sets the evaporate property on the
ellipsis overlays.  Emacs will delete them when the buffer contents
are zeroed out, which happens with `notmuch-refresh-buffer`.  This
prevents them from being collapsed to zero-width overlays in position
1.  See Emacs bug#58479.  An upcoming change in Emacs will make these
dangling overlays visible to the user.
