[TT-11091] Fixing Keys method to fetch all the keys when scanning

[mativm02]

Description

There was an issue when trying to fetch keys from Redis. The scan method wasn't being iterated, making it not return all the expected keys. It has been fixed, and a test with 50 keys has been added to ensure it works as expected.
