devise: Remember_token always regenerated when user logs in: existing one never kept anymore

In commit https://github.com/plataformatec/devise/commit/c92996646aba2d25b2c3e235fe0c4f1a84b70d24 a change was made that causes remember_tokens to be regenerated without checking whether the old one has expired. This causes a problem when users log in on multiple browsers or devices. Every time they log in, their session on other browsers/devices is invalidated, because a new token is generated.

My project is forced to stick with Devise 3.5.3 because of this breaking change. The fact that the commit I mentioned still contains a TODO is probably indicative of the fact this is a problem to be resolved.
