LibJS: Check validity of computed_property_name() result before using it This fixes two cases obj[expr] and obj[expr]() (MemberExpression and CallExpression respectively) when expr throws an exception and results in an empty value, causing a crash by passing the invalid PropertyName created by computed_property_name() to Object::get() without checking it first. Fixes #3459. 2020-09-12 12:22:36 +03:00			`test("Issue #3459, exception in computed property expression", () => {`
