TaskPanel: Fix assertion
When loading an .rviz config with MTC displays disabled, the mainloop_job to create a TaskPanel will never be executed (because the display is disabled). Removing the display will then hit the assertion that DISPLAY_COUNT > 0. Fixed, by not relying on Display::update, but just scheduling a Qt GUI job via QTimer::singleShot().
