HMI sends OnDriverDistraction notification to SDL twice

[ONyzhnyk-Luxoft]

Preconditions:

1. Start SDL and HMI
2. Connect mobile device via any transport
3. Register app and activate app

Steps to reproduce:

1. Check the “DD” box
2. Uncheck “DD”

Actual result:

HMI sends an OnDriverDistraction notification to the SDL twice, and the mobile application receives two notifications

- HMI→SDL: "OnDriverDistraction"( "DD_ON" )

• HMI→SDL: "OnDriverDistraction"( "DD_ON" )

• SDL→MOB: "OnDriverDistraction"( "DD_ON")

• SDL→MOB: "OnDriverDistraction"( "DD_ON")

• HMI→SDL: "OnDriverDistraction"( "DD_OFF" )

• HMI→SDL: "OnDriverDistraction"( "DD_OFF" )

• SDL→MOB: "OnDriverDistraction"( "DD_OFF")

• SDL→MOB: "OnDriverDistraction"( "DD_OFF")

Expected result:

HMI sends one OnDriverDistraction notification to the SDL, and the mobile application receives one notification:

- HMI→SDL: "OnDriverDistraction"( "DD_ON" )

• SDL→MOB: "OnDriverDistraction"( "DD_ON")

• HMI→SDL: "OnDriverDistraction"( "DD_OFF" )

• SDL→MOB: "OnDriverDistraction"( "DD_OFF")
