Message.replies can throw exception if there are no replies

Error: type 'String' is not a subtype of type 'int' of 'index'
Message.replies (package:draw/src/models/message.dart:53:37)

This occurs when there is a message with no replies. I believe the issue is that data['replies'] returns "" instead of null.

Also, FWIW, there is a typo in the method doc. It should be "Returns an empty list" instead of "Returns and empty list."

I know this is late but:

1. Once i get to this point in my app, I will test and provide a solution

2. A full stack detail would have been handy, as i am not sure if its you doing something wrong or DRAW, because this error means you are trying to access a Map<int, dynamic> or a List with a String using the [ ] operator. Which would just not work.

This should get fixed as #204 gets resolved.
