Fix session token issue

In _User collection a field _session_token is present and if you fetch
the user data form server, this field override the sessionToken saved
in your browser.

If you don't fetch the user, all request to server contain the right
sessionToken and if you fetch the user data from the server, all next
requests will contain the wrong sessionToken come form the
_session_token in user data fetched.
