Fix V display update when Vread is not supplied in the callback

Function `updateHistory` can be called with or without a supplied Vread. If Vread was not supplied that defaulted to `g.Vread` (global read-out voltage). However the default parameter assignment is taken at the moment the function is instantiated. So it was impossible to implicitly propagate the update Vread value to `updateHistory`. That now defaults to None and the value is read the moment the function is called. This is a backport from the pypify branch
