the cleanup not working

[qwy]

my gratitude first for using this cute implementation of koa-generic-session store

but i doubt whether the cleanup works for the set time (15 * 60 *1000) for it continue to grow even if i set the interval to a small one, like 2 * 60 *1000

could you fix it? or correct me if i'm wrong.

thanks!

Why don't you propose a change and issue a pull request. I am no longer working with MySQL - so I might not be in the best position for it.
