Andreas Kling bef09b899c LibJS: Fix object rest destructuring with MemberExpression target ...

When the rest element in an object destructuring assignment targets a
MemberExpression (e.g. `({a, ...t.rest} = obj)`), we were incorrectly
storing the original source object to the reference instead of the
rest object produced by CopyObjectExcludingProperties.

For example, `({a, ...t.rest} = {a:1, b:2, c:3})` would set t.rest
to `{a:1, b:2, c:3}` instead of the correct `{b:2, c:3}`.

The fix is to pass the result of CopyObjectExcludingProperties
to emit_store_to_reference instead of the original RHS.
