Fix crash when conversation scrolled window child changes.

Browse source 
This is a workaround for GTK+ Bug 778190.

* src/client/conversation-viewer/conversation-viewer.vala
  (ConversationViewer): Replace the whole conversation scrolled window
  when changing the conversation, not just the viewport.

* ui/conversation-viewer.ui: Remove the ScrolledWindow for now since we
  are constructing it manually.
