Accept null playback controls when Alexa sings

[rtchagas]

The MediaSession is not being updated when Alexa sings.

This is because Moshi crashes when trying to parse the RenderPlayerInfo.

error: com.squareup.moshi.JsonDataException: Non-null value 'controls' was null at $.payload.control

AACS expects the 'controls' field of the RenderPlayerInfo object to be non nullable but this is not the case when Alexa sings.
