Prevent duplicates

[mathieujobin]

Describe the bug
When we don't merge the PR, or let the repo unsupervised, new PR gets added every other day with the same changes.
Could rubocop_challenger check if the PR is already open, and either open a PR fixing a different rule automatically, that would be best.
or do nothing if that's simpler first step.

Hi, @mathieujobin

Hmm... I think this is not a bug, but an operational issue.
You can reduce rubocop challenge execution frequency. If you want to open a PR fixing a different rule, you can use a random mode that:

rubocop_challenger go \
  --email=email@example.com \
  --name=your_name \
  --mode=random

But I also want to prevent duplicates. Please see #205.
I will try. Thank you.

Thank you for the suggestion of using --mode=random I think that will help a lot

I will close this since this is duplicate of #205
