Bug 836690 - [SMS] Implement temporary in App message informing the user that they have started another SMS packet

Please note the in sms we got another rule about `maxConcatenatedMessages`. It defines the maximal  concatenated segment per sms. If  a message contains the segments more than this value, we will convert the message to mms and display a toaster that we convert the message into mms. In this case we don't have to show the segment information toaster.
