_match_applications: catch SwMatchError e.g. if permission denied

There are some SIM cards (e.g. those of sipgate), which return
an undefined error status word if one tries to select some of the
applications the card itself lists in EF.DIR.  Let's handle this
situation gracefully rather than printing python exceptions.
