### Description

In [NetflixSession.py#L256](https://github.com/asciidisco/plugin.video.netflix/blob/master/resources/lib/NetflixSession.py#L256) the comparison of the expire time selects the oldest cookie. I think it should be `expires < exp` (resp. `exp > expires`). Once the first cookie will expire, the speed will drop for all `Netflix.router()` calls.

I also looked into the cookie-db and found a cookie with `expires=3697214258` (year 2087, it will never expire); maybe this will create problems, I'm not sure.

Read resources/lib/NetflixSession.py at line 256 and trace how cookie expiration is compared before Netflix.router() calls. Verify the intended selection using the noted far-future cookie value, then confirm the corrected behavior with the relevant session flow.
