Hello.
This PR adds a test case where PropertyBindingInitialization performed in two cases of BindingInitialization throws when value is non-iterable. I will address those two cases separately below.
Check 1 covers
ObjectBindingPattern: {BindingPropertyList} {BindingPropertyList, }. PropertyBindingInitializationis performed in step 1
Check 2 covers
ObjectBindingPattern: {BindingPropertyList, BindingRestProperty} PropertyBindingInitialization is performed in step 1.
In both cases, BindingPattern : ArrayBindingPattern is reached beacause of
x: []. As a result, GetIterator(obj, kind) where obj isundefinedis called. Getiterator calls GetMethod(obj, %Symbol.iterator%) in step 2, which calls ToObject(object). Because object isundefined, ToObject throws TypeError.
