Talk Users are not created with project copy

[lcjohnso]

Current Behavior: ProjectCopier (link) does not create Talk roles along with Panoptes project roles, creating a situation where the owner/collab or any project team member cannot moderate or take other non-public actions on their project Talk.

Example Error: When the project owner tries to add collaborators via the Lab, a generic error message is displayed.

However, a look at the network tab shows that the error specifically has to do with Talk permissions, resulting in 401 responses to requests to create new Talk roles for collaborators (likely because the logged in user, the project owner, didn't have admin permissions to add other roles).

Also: even after the error message in the Lab, after reload the Panoptes aspects of collaborator roles all work correctly -- hence the explanation that the error is solely to do with Talk roles.

Desired Behavior: Create Talk roles along with Panoptes roles when ProjectCopier runs.

Potential Solution: add Talk client call for role creation to ProjectCopier, executing actions such as those described in the Stack Overflow entry regarding project ownership migration:

talk_client = TalkApiClient.new
talk_client.roles.create(name: "admin", user_id: project.owner.id, section: "project-#{project.id}")
