Update IdentifiableCookie.java

[Eluch]

Skip secure flag check on equals and hashCode generation.

My problem was that a server sent a set-cookie with "secure" and "HttpOnly" flags, then later after logout it sent a similar set-cookie without those flags.

The "SetCookieCache" java class then had it duplicated in the cookies Set (it should have replace the old one).

I wrote a PHP script to test how chrome handling this (i used https for the tests to be sure):

<?php
$iter = $_GET['iter'] ?? 1;

if ($iter == 1) { 
    setcookie('cookie_test_s_h', 'test', time() + 3600, '/', '', true, true);
    setcookie('cookie_test_s', 'test', time() + 3600, '/', '', true, false);
    setcookie('cookie_test_h', 'test', time() + 3600, '/', '', false, true);
    header('Location: ?iter=2');
} else if ($iter == 2) {
    // exit; 
    setcookie('cookie_test_s_h', 'empty', time() + 3600, '/', '', false, false);
    setcookie('cookie_test_s', 'empty', time() + 3600, '/', '', false, false);
    setcookie('cookie_test_h', 'empty', time() + 3600, '/', '', false, false);
    header('Location: ?iter=3');
} else { 
    echo 'Done';
}

After the first iteration:

After the second iteration I got the result what I expected:

TL;DR

This commit fixes the duplicate cookie problem what happens when the following situation happens:

set-cookie: as=SOME_TOKEN_HERE; expires=Fri, 17-May-2019 16:17:01 GMT; path=/; secure; HttpOnly
set-cookie: as=; expires=Thu, 16-May-2019 16:12:02 GMT; path=/
