Stale issues closed by pull request or manually should have the stale label removed

[angleKH]

The problem

In some repositories, the stale label has a description that explains it means the issue is 'closed, but still valid'. This means that contributors can also search through closed issues with the stale label to look for valid issues. However, if an issue was first stale, and then later fixed and closed, the stale label still remains and isn't removed. This makes it difficult to tell whether closed issues marked stale are valid or not.

The solution

Issues that were closed not by the stale bot should have their stale tag removed. If it was closed by a maintainer, it was either fixed or the maintainer came to a decision to not fix it and explicitly close it. Either way, it was not closed due to being stale and should no longer have the stale label.
