Allow the machine manager to set an empty active machine

Gracefully handle the case where the machine manager is requested to
delete the last machine in Cura. In this case, instead of deleting
everything of this machine and still keep it as an active machine,
the machine manager will set the active machine to None.

The QML files which depend on the active machine were changed to
properly handle themselves when there is no active machine.
