Description of the bug

Build-and-push workflow allows to checkout and create a branch at the beginning of the workflow, but the step right after tries to pull it and fails

Reproduction instructions

• prepare a repository that uses build-and-push
• configure build-and-push to listen to branch events and to use a branch to store assets
• don't create the target branch
• run the workflow

Expected behavior

The workflow doesn't fail, because it understands that the branch has just been created by itself
