don't crash when attempting to access properties of a JS Object that belonged to a deleted script engine
When the engine is deleted, the JSValue is invalidated, but the
QScriptValue's type will still be QScriptValuePrivate::JSC.
Use a new helper function, isObject(), that checks both that the
value is of type JSC _and_ that it is valid, before calling
JSValue::isObject() (JSValue::isObject() assumes that the value
is valid).
