extensionSystem: Don't load extensions multiple times

Browse Source 
Right now if XDG_DATA_DIRS is set to have duplicate entries,
then the extension system will try to load all extensions
more than once.

This commit prevents an extension from getting repeatedly
loaded by checking if its uuid is already registered.
