Properties: make query cache reference count aware.
The property query cache was not reference count aware and this could cause
problems if the property store removes an algorithm while it is being returned
from an asynchronous query. This change makes the cache reference count aware
and avoids disappearing algorithms.
A side effect of this change is that the reference counts are now owned by the
cache and store.
