bugfix: memory cache was not functional.
bugfix: memory cache was not functional.

This bug was caused by the bugfix of long names where I created complex key object.
I forgot to change memory cache to use the object, and use the "hash" as the key, the result was that every cached object
was different from each other, this resulted in non optimal performance as we can obtain from seedcache and test memory groth as
every key object was different from eachother
