Ignores closed security issues on Crawler
What does this MR do?
Ignores closed security implementation issues fetched by the Crawler
When fetching associated security issues and security merge requests from the Security Release Tracking Issue, we're filtering out closed merge requests, as we don't care for those. This commits also filters out closed security implementation issues, since those are not processed on the Security Release.
