Fix reauth logic so it can handle token response where error response is a string instead of dict. Similar issue see #857

in continuation from above comment.
In other words, i would like to understand what should be the expected behaviour of the method for the below test case?

with mock.patch("google.oauth2._client._token_endpoint_request_no_throw") as mock_token_request:
mock_token_request.return_value = (False, _REAUTH_NEEDED_ERROR, False)
with pytest.raises(exceptions.RefreshError) as excinfo:
reauth.refresh_grant(
MOCK_REQUEST,
"token_uri",
"refresh_token",
"client_id",
"client_secret",
scopes=["foo", "bar"],
rapt_token="rapt_token",
enable_reauth_refresh=True,
)

whether RefreshError exception is expected or whether reauth refresh flow (i.e., 354-364) is expected since enable_reauth_refresh=True and reponse_data=_REAUTH_NEEDED_ERROR?

@clundin25 , please let me know your thoughts on this.

[arithmetic1728]

I believe in case of reauth needed error, the oauth2 token endpoint always returns a json, in other words, something like mock_token_request.return_value = (False, {"error":_REAUTH_NEEDED_ERROR, ...}, False). The server won't return mock_token_request.return_value = (False, _REAUTH_NEEDED_ERROR, False) as described in the test case you mentioned.

[glabdulhadi]

ok. then agree.

[clundin25]

@arithmetic1728 perhaps enable_reauth_refresh=True should just be an early return in the function?
