Fix default behavior for DatabaseResourceAssignmentProcessor

If a data-dictionary did not declare an endpoint-selector, it would
default to primary cds-db instead of using data-dictionary source to
look up database configuration. Processor-db configurations were not
used because of this.

Also improved error messages and some refactoring.
