Add handle type value when initialize config
When client initialize the vc_config_mgr, manager and setting client send the handle with unique
type value as a parameter into. This is because the uid can be used to check the type of client
when vc_config_mgr needs to identify the client. However, widget client did not add unique value
into the handle.
Thus, this patch makes the widget client send handle with unique value for widget client. By this
change, widget client also works same as other types of client.
