Title: Fix joyride error

Hi,

Because of #5511, when the joyride is included on the page but hasn't been started yet,
the keystrokes events are still catched and we end up with a JS error
on `go_next` or `go_prev` functions.

This fix checks that the joyride is on screen before calling theses callbacks.

Thanks, and sorry for the error !
