If modemmonitor crash for some reason, status bar is not updated. The
reason is that statusbar check if modemmonitor is running, which it is
when trying to shutdown itself.
We change the way modemmonitor is detected using a single modem state
file. If the file is not present, then the monitor is considered not
running.
This single file permit to add more state in the future, without adding
any more files.
We also add a sleep 1, look like it is required to have instand status
bar update.
