When doing updates for composer.json files, which require symfony/flex, they fail since a few ~~weeks~~days with the following error:

Command failed: git stash pop || true
Too many revisions specified: '||' 'true'

Note

This only happens if symfony/flex is installed (probably due to https://github.com/renovatebot/renovate/blob/42.70.3/lib/modules/manager/composer/utils.ts#L15, https://github.com/renovatebot/renovate/blob/main/lib/modules/manager/composer/artifacts.ts#L166-L174 and https://github.com/renovatebot/renovate/blob/42.70.3/lib/modules/manager/composer/utils.ts#L83-L91).
