Checks whether there are any field mappings which are orphaned or any fields which don't have a mapping. An orphaned mapping means a mapping of a mappable field which isn't a mappable field anymore (e.g. it's deleted, has now a value type as its type)). All orphaned mappings are removed. All fields which don't have a mapping will get one.
