Fix bugs in class-field template and case files

- Correct property access in class fields template
- Remove assertions for properties which aren't present
- Correct expected assertion value for uninitialized class field
- Correct expected property descriptor attributes
- Fix property tests in class-fields/string-literal-names.case
- Pass restore option, otherwise it's not possible to call the method later
- Fix async iteration tests to test iteration result objects
