Crash when finding printer ID when no printers attached

[vladbabii]

I selected the option to get printer id with nothing attached

<!!!!> Make sure your printer is the only USB device connected!

###### Identifying the correct USB port ...
ls: cannot access '/dev/serial/by-id/*': No such file or directory

Issue is at line https://github.com/th33xitus/kiauh/blob/b6c07fc3572fba3b9bfa82323c3f59be965123d0/scripts/functions.sh#L153

It needs to be something like

if  [ -e /dev/serial/by-id/* ]; then 
  if [ -e /dev/serial/by-id/* ]; then
      status_msg "The ID of your printer is:"
      title_msg "$USB_ID"
    else
      warn_msg "Could not retrieve ID!"
      return 1
    fi
else
   warn_msg "Printer not plugged in or not detectable by serial id!"
   return 1
fi

I fixed the issue and extended the function to scan by path as well if it can't find the id for whatever the reason might be.
If you want to test the fix, you can find it in the dev-2.0 branch for now. Maybe you can give some feedback so i can already merge it into master if it works out for you.
