Temporary remove resource-display caching

An instance of ResourceKey may correspond to different instances
of Resources at different points in time. This can lead to old
instances of Display returned from cache even if resources have
changed.
We need to ensure 1:1 correspondence between Resources and
ResourceKey before using this kind of cache. Disabling it for now
to fix CTS.
