pySim-shell: check presence of runtime state before accessing it
When the command equip (do_equip) is executed, it accesses
self.rs.profile to see if there are any commands that need to be
unregistered before moving on with the card initialization.
However, it may be the case that no runtime state exists at this point.
This is in particular the case when the card is completely empty and
hence no profile is picked and no runtime state exists.
