domainGeneratorConnector: allow empty arguments

The domain generator was using the "merge delimiters" behaviour of the
tokenizer which made it impossible to have empty tokens; e.g.:

- empty rules;
- empty config/domain names (even though this is forbidden, this is not for the
  generator to decide);
- empty string parameter value;
- ...

It now uses the new "don't merge delimiters" behaviour.
