Fix - Harmony message length

Browse source 
Harmony 21.1 doesn't have QDataStream anymore.

      This means we aren't able to write bytes into QByteArray so we had
      modify how content lenght is sent do the server.
      Content lenght is sent as string of 8 char convertible into integer
      (instead of 0x00000001[4 bytes] > "000000001"[8 bytes])
