Don't do anything when the Messaging app isn't the default sms app

Bug 7466009

The messaging app has a number of services. In the past, there have been
ways to "trick" these services into sending a message, even though the app
isn't the default SMS app. Only the SmsReceiverService was protected with
an isSmsEnabled check. This CL adds the check to the other potential message
sending services.
