BUG/MEDIUM: vars: run over the correct list in release_store_rules()

Browse Source 
In commit 9a621ae76 ("MEDIUM: vars: add a new "set-var-fmt" action")
we introduced the support for format strings in variables with the
ability to release them on exit, except that it's the wrong list that
was being scanned for the rule (http vs vars), resulting in random
crashes during deinit.

This was a recent commit in 2.5-dev, no backport is needed.
