[GTK] Fix showing sidebar and tabsbar

- Fixed the sidebar position not being restored by applying the config
  value in main_window first_show and updating config in position
  callback.
- Renamed the main_window vpaned and hpaned widgets to aid identifying
  purpose.
- Fixed filtertreeview KeyError when not conneted and hiding tabsbar.
- Fixed the tabsbar notebook not being hidden on restart by adding a
  new config value.
