[IdealoBridge] Fix (#4316)
When a product was available before as used product in the past, and
now it's not available used anymore, a price update article was
generated on every feed loading, because the old used price was still
stored in the cache, and therefore different as "no price".

The issue was also present in the cas of a New product price that
becomes unavailable.

Now, when either there is no New or Used price available, the previous
price is delete from the cache.
