Fix output for commands that do not return entries.

I also changed the default value of the print_all argument in
textui.print_entry from False to True. It think it makes more sense this
way, because:

1) if order is None, it will still print something
2) if order is not None, it will print what's in order first and then the
   rest
3) commands that care about the print_all argument have to set it in any
   case, those that don't care usually want to print everything
