`platform activities` always use the project on local, ignoring `--project` or `env:PLATFORM_PROJECT`

I normally use ddev and I have a PLATFORM_PROJECT setup. On some projects, however, I sometimes want to switch across other projects.

I have this project that pushes to a drupal multisite, and I am in the process if splitting it to the their own project. So I have a branch project1, this is pushed to the main repo (the multi-site), but it's also the production branch of a another project.

If I export a new PLATFORM_PROJECT for project1, most commands work, but when I do platform activities it always prompt me to select the environment even though the branch name is right. The project is properly selected, but when it tries to get the environment because the input project (through env var or --project) is different, it just doesn't select any environment:

legacy-cli/src/Command/CommandBase.php

Line 751 in ac5cce2

|| ($expectedProject !== null && $expectedProject->id !== $project->id)) {

And it gives me to choose one from.

I don't expect this to work like this, what I would expect is for cli to realize that this is a valid environment/branch in my input project and just provide me the activities.

My current stack trace: (I manually throw an exception on the function to get it). I was using a cloned client from this repo.

I was trying to come up with a PR but I had the feeling that I was going to get messy and hard to contribute so probably best if I run it by you guys first and maybe you can come up with something a lot quicker having the full context of this.
