"Remember me" option on login page do not always work

[lostmsu]

Description

I basically hit this one, and it is annoying: #778

TL;DR; even if you "Remember me" you have to login periodically.

I believe the handling here is incorrect. If I keep coming to my Gitea instance this cookie needs to be updated periodically, or should never expire in the first place
