Keep shuttle ctrl in sync with actual speed

Browse Source 
When using "VS" the numeric control shows the "default speed"
when not rolling. Then when starting to roll default speed will
be the actual speed.

Previously the shuttle was not updated when `last_speed_displayed`
was the current speed. This dated back to before "VS" showed
default speed.
