KNL-1011 - Fix caching/lazy loading by copying loaded flag properly

The m_fullyLoaded flag was not being copied over properly when sites
were copied. Since sites are always cached as copies, the flag was
always false in the cache. This was causing significant reretrieval of
sites.

Big thanks to Sam O for the debugging and patch.
