Fixes Proxy getter issue

When the object $value is an array and the script tries to access
to an exixting index, the getter returns the interger instead of
the proxy with the actions.

E.g.

TypeError: Object 1043 has no method '$get'
    at <error: illegal access>

Useless argument when calling proxyResponseHandlerREST
