Add isFullyAuthenticated to AuthenticatedTrustResolver

[jzheaux]

Since isFullyAuthenticated is a composition of isAnonymous and isRememberMe, a default convenience method can be added:

default boolean isFullyAuthenticated(Authentication authentication) {
    return !isAnonymous(authentication) && !isRememberMe(authentication)
}

This would be nice for SecurityExpressionRoot#isFullyAuthenticated and AuthenticatedAuthorizationManager#fullyAuthenticated

Yep! The issue is yours.
