chore: read datalayer metadata from file if missing in DB (#2494)

Browse source 
When we introduced the DataLayer.settings property, we did not run a
migration for existing datalayers (because there are millions in the
French server).
Now that we simplified the `DataLayer.isLoaded()` logic in the client,
we want to be sure that created DataLayer on the client have full
metadata.
