Set the same default token_value on all platforms

Remove "if defined(OS_CHROMEOS)" when setting default token_value in
SetRefreshTokenForAccount in identity_test_utils.

UserPolicySigninServiceTest was calling IssueOAuthToken with
"refresh_token_for_" + gaia_id value because they expect the refresh
token to have this value by default. Fix this test by calling
SetRefreshTokenForAccount with custom token value and using the same
token to issue OAuth token.
