Print ActiveHelp at the same time as other comps

If there are other completions to be shown, we print the ActiveHelp
messages at the same time instead of at the preceding tab-press.  Such
an approach provides a better UX where the ActiveHelp messages are
visible as if they were part of the real completions.
