app: do not catch exceptions in init_card

The function init_card catches all exceptions and then returns None objects for card or rs in case of an error. This does not fit in the style we pursue in pySim. This is in particular true for library functions. We want those functions to raise exceptions when something is wrong, so that we can catch the exception at top level. Let's fix this for init_card now.
