Jenkins and plugins versions report

What Operating System are you using (both controller, and any agents involved in the problem)?

OS: Linux - 4.14.326-245.539.amzn2.x86_64

Reproduction steps

1. Create Github organization with several repositories containing jenkinsfiles
2. Either configure organization webhook or 1 repository webhook with "Issue Comments" Event
3. Create and configure Jenkins "Organization Folder" job
4. Open a pull request in multiple repositories, so that multiple repositories have the same PR number (e.g. pull request Support GH organization folders #1 on multiple repos)
5. Trigger a scan in the Jenkins organization to detect and create jobs for these repositories
6. Post a comment in one of these repositories with the keyword configured in the plugin

Expected Results

The expected result would be that a build is triggered only in the repository in which the comment was posted

Actual Results

Builds are triggered for every "repository" in Jenkins that matches the PR number which sent the Github event

In the image above, a comment with the expected keyword was posted on first PR in the sw-prj-repo3 repository

Anything else?

Here is a log snippet:

Is this the intended behavior?
