Improve logging of the number of entities

[ondretom]

It does not make sense to print the number of entities here because they are processed on line 64

skill-sdk-nodejs/lib/nlu/bundles/engines/wcs/nlu.js

Line 56 in 3eaadfb

' ' + this.name + ' [' + intent.intent + ', ' + intentity.getNumOfEntities() +

[ondretom]

Logging info should be also present in entities part (in case when there are only entities we know nothing about progress in wcs nlu)

skill-sdk-nodejs/lib/nlu/bundles/engines/wcs/nlu.js

Lines 61 to 66 in 3eaadfb

	if(result && result.entities && result.entities.length > 0) {
	// The entities
	result.entities.forEach(function (entity) {
	intentity.addEntity(entity.entity, entity.value, entity.confidence);
	});
	}
