lib: settings: find the first loaded instance of WpSettings when metadata_name is NULL

Browse source 
This allows changing the metadata name in the configuration file
and get all the Lua scripts looking at this new settings metadata
without requiring any other code changes. It can be useful in
multi-instance setups where we'd like the instances to be isolated
and load their own settings instead of relying on each other for that.
