Summary

This pull request closes #29 . The problem was the following code:

var request = new HttpRequestMessage(HttpMethod.Post, $"{logtoOptions.Endpoint}/oidc/token")
{
   Content = new FormUrlEncodedContent(body)
};

has added a double slash after the endpoint, because the endpoint already ended with a slash which resulted in a 404 Not found rejecting the cookie.
I have refactored this and added a new method GetOidcTokenRequestUri to the LogtoCookieContextManager that will safely add "oidc/token" to the endpoint. I also added some test cases to test this method.

Testing

I added a new test file with test cases that test the GetOidcTokenRequestUri method.
