prevent SimCardCommands.select_adf_by_aid bypassing lchan

Now that pySim-shell is aware of logical channels and issues almost all of its APDUs on the currently selected channel, we must also make sure that ADF selection by AID (implemented by the CardBase class) issues the SELECT on the respective logical channel.

Before this patch, SELECT ADF by AID would always be issued on the primary logical channel (0), irrespective of the currently active RuntimeLchan.
