Aurion Connector Schema Mappings Saving

When you add a new Aurion connector (mainly with the Generic one, but applicable to others too), configuring the schema options automatically generates schema mappings. These display on the UI, but don't validate until the connector is run. Therefore you get an error on the first run of the connector regarding schema mappings, which means you have to run the save action on the connector to get it to persist to config.

It would be good if the schema mapping defaults could be persisted to configuration when the schema is modified or connector enabled - that way if they're not valid the connector isn't able to be enabled. 

Currently an issue against IDB v5.3
