GUI: removed force federation authz for password reset

- This feature is not supported in IdP and SP
  communication. Hence we can't force user to re-login.
  Using it in current scheme causes all requests to
  end on WAYF page (not respecting successful authz).

  Normal federated login is now used when accessing pwd-reset.

TopGroupCreator can call getCompleteRichMembers and getGroups

eduGAIN group service call this methods at start and not when they are
really needed.
