Do not account for stopwords as much as we did

[alexgarel]

Currently we use stopwords to normalize entries, but this is wrong, Product Opener does not do this, it uses stop words only at matching time.

This leads taxonomy editor to think some entries are the same when they are not (eg. fruit juice concentrate vs fruit juice from concentrate) and may also rise synonyms positive that are not true positives.

Re-evaluate at each point where we use stop-words if we need them or not (for parent matching we might try both, but raising error if there is more than one match with stop words removed).
