    tests: fix minor issues
    
    * tests/actions.at: Fix some log messages.
    Prefer #error to fprintf: it fixes the invalid use of yyoutput in
    %destructor, and it is an even stronger check: that the code is not
    even emitted.  The portability of #error is not really a problem here,
    since the point is anyway to have the compilation fail.
