Primary output check for sonification is removed.

- When there are 3 different tracks (Ringtone, Music and Touchtone)
   the device switch happens for touchtones to primary if the primary
   output is active. This can lead to music being played in combo
   due to timing issue.
 - This is mainly because we have a check for, primary output if
   active we return true for SONIFICATION. This will set SONIFICATION
   for touch tones and this device switch will come after music device
   is set.
 - Hence music will start playing as SONIFICATION.
 - We have removed the primar output check for getting device strategy
