Polishing ubuntu-core-launcher slightly

[Gustavo Niemeyer]

We cannot keep the compatibility making it optional, unfortunately, because
"run-snap snap.app args" is ambiguous with "run-snap snap.app cmd args". We
cannot tell if the cmd there is part of the args or not. This would be a
breaking change.

We might keep compatibility by introducing a second command that works in a
different way, or by forcing a reboot and refreshing the launching scripts
on update.
