Incorrect $DONE handlers which led to calling $DONE twice
- async-generators/yield-promise-reject-next-yield-star-async-iterator.case
- dstr-assignment-for-await/array-elem-trlg-iter-rest-nrml-close-skip.case

$DONE handler not called at all:
- dstr-assignment-for-await/array-elem-put-const.case
- dstr-assignment-for-await/array-elem-trlg-iter-elision-iter-nrml-close-null.case

Incorrect assumed execution sequence in IteratorDestructuringAssignmentEvaluation:
- dstr-assignment-for-await/array-elem-iter-rtrn-close-null.case

- 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
