Cleanup

[dereuromark]

It seems some classes could need a bit of cleanup

authentication/src/Authenticator/CookieAuthenticator.php

Lines 77 to 78 in 33b4fa3

	if (!class_exists(Cookie::class)) {
	throw new RuntimeException('Install CakePHP version >=3.5.0 to use the `CookieAuthenticator`.');

impossible code to run into probably at this point
