ScrolledWindow: Fix non-disconnection of handlers

Browse Source 
• Use disconnect_by_data() to catch both _adjustment_changed() and now
  _adjustment_value_changed(), as the latter had been missed until now.

• Also disconnect from indicator_value_changed(), which was not done in
  destroy() due to indicator_reset() and remove_indicator() disagreeing.
