Fix swaybar axis event logic

Browse source 
Uses 'visible' instead of 'focused', since we may scroll on a bar which
isn't the focused output.

We can't use "next_on_output" or "prev_on_output" to implement this,
because it only modify the focused output. So scrolling on an unfocused
output will affect the incorrect one.

We just use the "workspace name" command instead.
