With xelatex everything is fine, but with lualatex

{} was never a completly reliable method to suppress a ligature (see
exercise 5.1 in the texbook), and obviously it now fails completly
The !{}` was _not_ an example for suppressing a ligature.
in luatex due to the changes in the ligature/hyphenation handling
(it doesn't work in context either).
it should show that there is something wrong.
csquotes should better insert either \/ or \kern0pt before the
ending quote.
that is another question.
