We specify that the return type of Exception::getMessage() is a string. However, we don't currently ensure this, because Exception::$message is a protected member that can be set to any type. Fix this by performing an explicit type-cast. This also requires a temporary refcount increment in the __toString() object handler, because there is no additional owner of the object, and it may get released prematurely as part of the __toString() call.
