Fixed potential issue with axes released before TravelToStartPoint

Function TravelToStartPoint was called aftrer calling
LockCurrentMovementSystemAndWaitForStandstill which releases all axes
not associated with the current tool. A tool change may also have taken
place, which will ave released axes ont owned by the new tool. So
TravelToStartPoint needs to allocate appropriate axes.
