History generator plots not updated when load new listing file.

[Angus Yeh]

This is because the line plot was replying on t2model's 'model_raw_data_changed' signal as implemented in the BaseDataSeries class.

This is wrong for the history plots, as lst.history() needs to be re-called as long as listing file is reloaded.

The block history used to work (luckily) because it's the same variables as those from t2model.
