Field guide's attached images not included in project copy

[lcjohnso]

Current Behavior

When the ProjectCopier (link) is run, the field guide's attached images are not copied over. Tutorial images images are copied over (see https://github.com/zooniverse/panoptes/blob/master/lib/project_copier.rb#L13) but field guide images are not.

Desired Behavior

Add field guide attached images to the project copier, possibly via the INCLUDED_ASSOCIATIONS target list.

Reopening: while media resources are cloned (good), the media item IDs in the field guide's items field remain unchanged, so the linked icon images still do not appear in the lab for the cloned project or in the field guide on the project (bad).

Example on prod: Cameras for Conservation / Cameras for Conservation EY
Project Source: ID=24811, https://www.zooniverse.org/lab/24811
Project Destination: ID=30326, https://www.zooniverse.org/lab/30326
Field Guide IDs = 3023 and 3140 for source and destination, respectively (note that both instances items values are the same)
