Fix shorthand property assignment type resolution

[auvred]

If you try to call getTypeOfSymbol on foo (shorthand property assignment), error type will be returned.

const foo = 1

const res = { foo }
//            ^^^

---

On line 11973 in checker.ts, declaration.name (not just declaration) is passed to checkExpressionForMutableLocation

    function getTypeOfVariableOrParameterOrPropertyWorker(symbol: Symbol): Type {
        // ...
        else if (isShorthandPropertyAssignment(declaration)) {
            type = tryGetTypeFromEffectiveTypeNode(declaration) || checkExpressionForMutableLocation(declaration.name, CheckMode.Normal);
        }
        // ...
    }
