Remove Registrar caching from all console actions

Caching turns out to be an anti-pattern for the console.  If we use it, changes from the user just get obliterated by the older, cached version the next time the console refreshes (and it happens to refresh after every update).  Caching is also not very useful here, as the amount of database access driven by the console is very small.
