Vincent Imbimbo 69e3b405d9 cex: fix reporting of null nonterminals
I implemented this to print A ::= [ ], but A ::= [ %empty ] might be
clearer.

* src/parse-simulation.c (nullable_closure): Don't generate null
nonterminal derivations as leaves.
* src/derivation.c (derivation_print_impl): Don't print seperator
spaces for null nonterminal.
* tests/counterexample.at: Update test results.
