Composer in project with branch alias sometimes refuses to install dependencies #8579
Description
My composer.json: https://github.com/phpstan/phpstan-src/blob/master/composer.json
When I run this command:
composer update
I get the following output:
- phpstan/phpstan-strict-rules 0.12.0 requires phpstan/phpstan ^0.12 -> satisfiable by phpstan/phpstan[0.12.0, 0.12.1, 0.12.2, 0.12.3, 0.12.4, 0.12.5, 0.12.6, 0.12.7, 0.12.8, 0.12.9, 0.12.x-dev].

But only sometimes. It works when I'm checked out on master. It always works in Travis CI, no matter if it's on master or a pull request or a tag. But it fails in Travis CI when I push some other branch than master, and it always fails in GitHub actions. See:
- https://github.com/phpstan/phpstan-src/pull/128/checks?check_run_id=426902574 (fails)
- https://travis-ci.org/phpstan/phpstan-src/jobs/646269381 (passes)
I'm not sure what's different in these cases and I'd expect it to work in GitHub Actions and also on other branches than master.
