Nop on PRs doesn't work for environments

[linus345]

Problem Description

safe-settings supports running in a nop mode which will report the changes that will happen in a PR comment. Recently Environments support was added in #544 but this does not seem to work with the nop mode. When we opened a PR adding an environment it went and applied those changes directly before the PR was merged to master.

What is actually happening

Opening a PR adding an environment to a repo will add it when running the nop mode in the PR checks and then not report any changes in the PR comment.

What is the expected behavior

Opening a PR adding an environment should report the changes being made in the PR comment and only apply the changes when the PR is merged to master.
