Fix display of before- and after-strings at invisible text

* src/xdisp.c (next_overlay_string): Don't raise the
ignore_overlay_strings_at_pos_p flag if the iterator is already
set to continue at a buffer position different from the one
where the overlay strings we just processed were loaded.  (Bug#25856)
