> EnhancementEngines need to check in the canEnhance(..) method if they can enhance a ContentItem.
> While the Lucene FST Linking engine does check for the language and the required NLP analysis results it fails to check if an fitting FST model is present.
> Because of that the Constructor of the LinkingSession throws an IllegalStateException as it expects such calls to be already rejected by the Engine.
> The fix is that the canEnhance checks if the configuration provides a FST model for the language OR a FST model for the default matching lanugage. If both is not available it needs to return EnhancementEngine.CANNOT_ENHANCE.
