Fix Dialog behavior

- Fix proxy dialog being callable multiple times
- Use smart pointers in more places
- _owncloudSetupWizard was guarded by a smart pointer,
  this needs to be accounted for in other code pathes.
  Fixes Setup dialog not showing up when left-clicking
  on unconfigured instances on Windows.
