Clean the test path after each spec run

Closes #5461

See merge request gitlab-org/gitlab-ee!5141

FactoryBot's build_stubbed ignores the current database sequence of the
projects table and starts at ID 1000. If more than 1000 projects are created
during a test run, leftover repositories can cause spec failures. For example,
a spec that expects an empty repository may fail since there may be existing
content.
