https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/4855 introduces a
change which nullifies issues.closed_at whenever one reopens a issue.
Which is not currently expected by the burndown charts. Hence we're now
using the events.created_at information.

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.

Closes #5461
