Remove 'disable validation' from RelationTreeRestorer
What does this MR do and why?
In !155732 (merged), we added validation for presence of an Organization on Namespaces. Since this MR was already quite big and impactful, most 'Create Namespace' code paths are wrapped in a Namespace.with_disabled_organization_validation
method, which caused the validation to be skipped.
This MR will remove this exception from Gitlab::ImportExport::Group::RelationTreeRestorer
and the descendant class Gitlab::ImportExport::Project::RelationTreeRestorer
.
