Bot tries to also handle old closed and merged pull_requests and runs into errors

[roydenwa]

The bot is used in a large repo with the following simple config:

blockingLabels:
- 'SKIP ALL'

requiredLabels:
- AutoMerge

deleteBranchAfterMerge: true

mergeMethod: squash

The error logs suggest that the bot is also trying to handle old closed and merged pull_requests.
Could this unwanted behavior be due to the fact that the getAssosiatedPullRequests function in index.ts sometimes returns all pull_requests for a certain repo?

The noticeable issue is that the bot looks a lot into irrelevant old, partially closed, PRs, but less into recent updated PRs. The effect is that PRs being ready to be merged stay unmerged for several hours.
