Failed imports should clean up the partially imported items
When a project import fails, whatever items are successfully imported remain, but re-importing them again fails because the project is already created. The automatic repository check feature will complain with something like this:
GitLab Admin | One project failed its last repository check
Steps to reproduce
Create a new project from an import
When the import fails, it should not have successfully created a project.
A project is created with partially imported data.
Relevant logs and/or screenshots
(Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise.)
Output of checks
One project failed its last repository check
Change import behavior to create the project only if the import was successful.
