Richard Hughes c1fc8a55e0 Always set the progress ID when setting the number of steps
This fixes a potential critical warning (seen in the hailuck plugin,
although others may be affected too) where the parent does not set the
ID before the child sets the number of steps.

It's much more helpful to have the child position for debugging anyway,
so just set it in all cases.
