Subject: [Qt] simplify ban list signal handling

- remove banListChanged signal from client model
- directly call clientModel->getBanTableModel()->refresh() without the way
  over clientModel->updateBanlist()

- also fix clearing peer detail window, when selecting (clicking)
  peers in the ban list
