fixed testcases
optimization
Added username as a restricted field on updates
Added that username will be treated as id when trying to get a user, or
delete one. Also added checks to make sure the given username in
creation is unique in the system and that it is given. Also added that
username is a restricted field when doing a update.
All the old tests now work
Fixed so that a single user can be deleted
Removed display
Now tests works again after change to user.erl
changed ranking to find ESId from the given username and search for that
in es
Fixed more errors that i caused in rankings
