The browsertest uses ProfileOAuth2TokenService as well.

This file can be converted to use the functions of identity_test_utils.h; the removal of SigninManager/ProfileOAuth2TokenService knowledge will then happen when the blocking bug is fixed. (i.e., we can convert this file even before the blocking bug is fixed).

Convert browsing_data_remover_browsertest.cc to Identity service

the auth error of a given account with a refresh token.
