We are specifying that we will only return the shared runners on two
condition; 1 if project has any available 2 if shared runners are
enabled.

2 is not correct. In the admin UI, when the user press "disable shared
runners" we still show the runners to show what kind of runners are
available when the user enables them. We want the API to mimic this
behavior from the UI.

This removes the `ForkedProjectLink` model that has been replaced by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.

Bamboo API returns an array of results as per
https://docs.atlassian.com/atlassian-bamboo/REST/6.2.5/#d2e786
