Log Message:
-----------
ReadableStream::cancel is not handling the case of an empty JSValue
rdar://165347557

Reviewed by Chris Dumez.
InternalReadableStream::cancel s returning an empty value in case of exception,
which cannot be jsCast.
We add null checks to prevent jsCasting empty values.
As a fly-by fix, we also remove some method declarations that are no longer
needed after the pipeTo JS built-in implementation removal.
Covered by added test.
