When ofono dies while connected using PPP, modem AT channel is not put
back to command mode (tested with HUAWEI modems E3372 and MS2372).
If ofono is restarted, it won't be able to connect as it gets no answer
to AT commands on this AT channel.
This patch adds a quirk to immediately send escape sequence on modem
channel when gprs-context atom is removed.
