Fixes for IDE tests after qualifier modifications:

- CallType should look into QUALIFIER,
 so that completion works for (companion) object qualifiers.
- Record type and reference target for object qualifiers (not only for companions).
- "Create (function/...)" should understand ClassQualifier as possible receiver.
- Cleanup after rebase on master.
