Title: Simply caching of TicketGet

Before there were three layers of Caches:
* An in-memory cache in TicketObject
* An in-memoy cache in CacheInternalObject
* A file cache

This commit removes the first one, because it's wasteful
with no benefit to have the same information in two in-memory
caches.
