setting expiration fails

[yeongjukang]

Hi I found an error at 'Save' method of 'session.go while I was using this package'.
I added log.Println and panic like code below and got log below.
It is also happens when I use 'memory' as provider. I think tinylib/msgp should be ready for time.Duration treating it as int64 or session to use int64 instead of time.Duration.

I think returning nil when there is an error is inappropriate too. '30s setting' didn't work every time and '2hours' was returned constantly and it made me to take some time to find out like this.

Thank you for such a nice library.

data, err := s.config.EncodeFunc(store.GetAll())
	if err != nil {
		log.Println(err)
		panic(err)
		return nil
	}

Hi @979156,

I've found the error. Tomorrow I will fix it.

About the not return the error, it was my mistake, maybe I didn't see that when I refactored the code.

Thanks you!

Fixed! 🎉
