added ANIMATION type const and fixed some bugs

In getUpdateType method, if a user sends his/her location or contact, the "message" type will return. 
As a result, for fixing this issue, we should change priority and push location and contact condition upper than  "reply".
It's same for "animation" and "document" type, because in receiving json from server animation data is upper than document
