The default stays the same -- false. A race could prevent setting ForeignMenu::_active correctly. That happened when Application::on_app_activated was called before _foriegn_menu was created. When foriegn_menu was created its _active defaults to false, and that has not changed, until focus was taken out and back in spice-client window. This caused usbrdr to sometimes not auto-share devices, unless the user switched focus to a different application and back to spicec. The fix updates ForiegnMenu::_active upon creation.
