Title: Fail silently if asset_sync is disabled

If asset_sync is disabled, we shouldn't expect to have a valid configuration file as we don't need it.
This prevents the library from raising an exception for things like "Aws access secret can't be blank" when the library is disabled, where we won't need them anyway.
