Fix infinite recursion under prettify-symbols-mode and linum-mode

* src/xdisp.c (get_overlay_strings_1)
(handle_single_display_spec, push_prefix_prop): Invalidate the
composition information before starting to iterate on a string.
Otherwise we might think in set_iterator_to_next that we are
delivering characters from a composition, and do all kinds of
nonsensical things, like over-step the string end.  (Bug#27761)
