I'm having expired cookies loaded using PersistCookieJar

[aletorrado]

Hi,

When calling loadForRequest I'm getting cookies that were expired long before even initializing PersistCookieJar with FileStorage.

I was looking into the code and found in PersistCookieJar that the _filter method that seems responsible for filtering expired cookies is only called on _save but not on _load.

Is this an expected behavior? I'm thinking about submitting a PR about this, but wanted to make sure that I was heading to the right direction.

Thanks
