PrologRuleEvaluator: Fix endless loop on type error

If a Prolog rule fails to load and PrologOptions#logErrors() is true
(which is e.g. the case if the request is being traced) there was an
endless loop in PrologRuleEvaluator:

1. typeError(String, Exception) is invoked which logs the exception and
   then calls typeError(String) with DEFAULT_MSG as parameter
2. typeError(String) delegates to typeError(String, Exception) with the
   exception parameter being null which brings us back to 1.

The issue was introduced by change I018ce9e13.
