Improved async/await usage

I am a PhD student in the CS department at the University of Illinois. I'm currently doing research on asynchronous programming in phone applications. I developed a tool that automatically improves async/await usages by doing transformations.

The tool found some opportunities in your application. There was no need to use async/await for 2 methods. It will decrease the overhead that is caused by async/await state machine and it will simplify the code. Removing async/await does not change the behavior at all.

Second, it added corresponding async calls of methods in JsonConvert class under "async" declared methods. For instance, it replaces "JsonConvert.DeserializeObject" with "JsonConvert.DeserializeObjectAsync".
