* Removed redundant code in RestService.cs

* Removed unchecked TryParse, replaced with Parse as we were not checking for success and could lead to weirdness if an exception is ignored.
* Removed unused variable m_newAvatar
* Removed several unused try{}catch(Exception e){}'s.
* Added null assignment in simpleapp to prevent warning.
