This helper is right on the limit of the number of calls being made.
When the request store is enabled, and Sidekiq is running in inline
mode, just a couple of additional actions result in it being pushed
over the line.
The operation is entirely artificial, since in reality we'd perform
these requests in multiple separate processes, so just whitelist it
for now.
This removes the `ForkedProjectLink` model that has been replaced by
the `ForkNetworkMember` and `ForkNetwork` combination. All existing
relations have been adjusted to use these new models.
The `forked_project_link` table has been dropped.
The "Forks" count on the admin dashboard has been updated to count all
`ForkNetworkMember` rows and deduct the number of `ForkNetwork`
rows. This is because now the "root-project" of a fork network also
has a `ForkNetworkMember` row. This count could become inaccurate when
the root of a fork network is deleted.
