It wouldn't be a bad idea, though, to include the AT command retries
logic directly within mm_base_modem_at_command(), so that whenever we
get a SIM_BUSY error we automatically do the 2s delay and retry,
regardless of the command we sent. We could also let plugins modify the
list of errors which should be considered to get retried... Just an idea.
