`AbstractRememberMeServices::encodeCookie()` guards against `COOKIE_DELIMITER` in `$cookieParts`.

* it would make `AbstractRememberMeServices::cookieDecode()` broken
* all current extending classes do it anyway (see #14670 )
* added tests – it's not a public method, but it is expected to be used by user implementations – as such, it's good to know that it works properly
