Zamir Martins requested to merge default_branch_image_returns_nil_when_not_gitlab into master Nov 12, 2021

Why is this change being made?

Decouple default_branch_image from GitLab variables which might not be present when running without integration.

Therefore default_image_branch won't be present when the required variables are not present.
