Describe the bug

See here: https://github.com/openiddict/openiddict-samples/blob/dev/samples/Velusia/Velusia.Server/Controllers/AuthorizationController.cs#L65

according to the spec Note that max_age=0 is equivalent to prompt=login but that is not 100% correct, because if I use max_age=0 I will have an endless loop, because if max_age=0 the prompt values needs to be removed when creating the redirect_uri as well

To reproduce

run velusia example call the client with max_age=0

Exceptions (if any)

none, you will just redirected infidentily
