Normally when a project is created, `Projects::CreateService` attempts
to initialize a Git directory and update the `.git/config` to include
the human-readable project full path.  However, for forks and project
imports, the repository is imported in a separate background job
(e.g. RepositoryForkWorker, RepositoryImportWorker). As a result,
attempts to write to the `.git/config` directory will fail unless the
job has completed first.

https://gitlab.com/gitlab-org/gitlab/-/merge_requests/35305 will ensure
that the `.git/config` is updated after the import is successful. This
commit will prevent attempts to `.git/config` for project imports and
forks from occuring right after project creation.
