Messages are now sent as type 'text' instead of 'unicode'.

Making a messages as type 'unicode' unnecessary splits it after 70 chars!
(Ref: https://docs.nexmo.com/index.php/sms-api/send-message)
This was causing our messages to be 'magically' (almost untraceably) be
split into multiple parts and charge us a hefty amount!

Also, it seems that our original motive of using 'unicode' which was to
allow accent and other such things from French alphabet, is already satisfied
thanks to the encoding in utf-8.
