Refactor and enhance CookieNamesTests methods

Refactored and renamed several test methods in `CookieNamesTests` to improve clarity and align with updated functionality. Replaced methods testing `GetEnvelopeReceiverKeyOrDefault` with new methods for `GetEnvelopeReceiverCookieName` and `GetEnvelopeKeyOrDefault`. Added new tests to validate behavior with default cookie names and incorrect bases. Renamed `TryGetEnvelopeReceiverKey` methods to `TryGetEnvelopeKey` for consistency, while maintaining their functionality.
