MBL-1213: Stop sending token as query param for V1, send the token as basic auth header

[Arkariang]

📲 What

• Removed token as query paramenter for V1 endpoints
• Added token as header for V1
• Old V1 endpoint /xauth/access_token returned user and token as response, reason why CurrentUser login method required both parameters, with the new endpoint /v1/oauth/authorizations/exchange we first obtain the token and later on request for /v1/users/self.
• Refactor CurrentUser , CurrentUserV2 and LoginUserCase to handle separately token and user

🤔 Why

• Token as query param is a huge security risk

📋 QA

No user facing changes for this one, you should be able to navigate/ login out with ffon and ffoff as usual.
But you can take a look at the network inspector, check for V1 calls and see how there is no token as query param :)
