After a profile switch the shell was unusable: every file select failed
with 'Attribute already exists: do_decode_hex (ShellCommands)' and even
equipping did not help - only a server restart recovered it.
pySim's equip() unregisters only the command sets of the file that is
selected at that moment, then re-registers everything while selecting
MF/EF.ICCID and MF with the app as cmd_app. esim._select_isdr() selected
the ISD-R ADF without cmd_app, so MF's sets (ShellCommands, ...) stayed
registered while the selection moved to the ADF; the equip after the
profile switch then died re-registering them (cmd2 raises
CommandSetRegistrationError), leaving the app broken.
- _select_isdr() passes the shell app as cmd_app, so the old file's sets
are unregistered and the ADF's (none) registered.
- _restore() passes it to soft_reset() too, so the MF re-selection updates
the bookkeeping on both the success and the failure path.
- _esim_reinit() probes select('MF', app) after the equip and reports
reinitialized: false on a registration error (a card-level select
failure, e.g. no active profile, is tolerated).
- tests assert the cmd_app plumbing on the ISD-R select and the restore
(profiles, chip and both switch paths).
