reset_session doesn't change session_id

[enewbury]

Steps to reproduce

Setup session to use cache_store.
Create two controller endpoints, get_session, and reset_session
The get_session simply returns the data in the session(which instantiates the session)
The reset_session calls "reset_session" and then returns the session.

Expected behavior

Expect to see the session_id in the cookie change after reset_session is called

Actual behavior

The same session_id is returned after calling reset_session.

System configuration

5.2.2

Ruby version:
2.6.1

Research

The destroy method of the ActionDispatch::Request::Session should work similarly to the Rack::SessionHash by reseting the cached 'id' to what is returned from the SessionStore "delete_session" method.

    def destroy
        clear
        options = self.options || {}
        id = @by.send(:delete_session, @req, options.id(@req), options)
        options[:id] = id if id.present?
        # Load the new sid to be written with the response.
        @loaded = false
        load_for_write!
    end

Closing because I found the way to address this within my Custom SessionStore, so no need to change in rails.
