Receiving a remote data track message throws a `Unhandled Exception: type '_InternalLinkedHashMap<dynamic, dynamic>' is not a subtype of type 'Map<String, dynamic>'`

Current bug behaviour

When a remote datatrack message is received it throws a Unhandled Exception: type '_InternalLinkedHashMap<dynamic, dynamic>' is not a subtype of type 'Map<String, dynamic>'

Expected behaviour

That the message is received without an error

Steps to reproduce

Start the example app, make sure at least 2 participants are connected and wait for a minute when the example app sends a datatrack message.
