Currently, if we reach a "conflicting" case in a codeflow subscription when the source repo is adding dependency Foo and the target is removing it (or vice versa) we throw an exception, and never push a commit or anything like that. This can lead to a PR not being created at all, which is undesirable behavior.

Goal

• Don't throw an exception in this situation, except what the target branch has
• Ideally put a comment in the PR so the PR reviewers are aware that this happened
