    xi2: XSync before getting the client pointer on construction
    
    If the device manager is created and queried for the client pointer at
    a very early stage in application lifetime, the device_id returned would
    be 0 as the server hasn't apparently decided yet about the client pointer.
    
    For these situations, doing XSync prior to fetching the client pointer
    gets the server to device about the client pointer before we query it.
