[IdealoBridge] Really fix Logic and enhance Feed Content (#4321)
- Fix Feed Title generation (wrong usage of loadCacheValue)
- Use a more reliable way to get New and Used Price
- If no new Price and no Used Price are present in the page, then don't
  delete previous New Price and previous Used Price
- If there is no New Price and no Used Price, then return no Feed
  Item
- Fix the "now" date format
- Make the Feed Item Title more readable
- Use the Product Link as the Feed URL
