Collection "page" `id` values do not match URI

[mathewjordan]

It looks like the id for "pages" for any Collection not being the first/initial do not match the expected URI. They instead render out the initial Collection URI (without the included /# as their value.

For example, every Collection traversed in the usgs_tx Collection is provided with the id for the initial Collection.

These would be the id values for each of these Collection pages:

2. https://iiif.archive.org/iiif/usgs_tx/2/collection.json ➜ https://iiif.archive.org/iiif/usgs_tx/collection.json
3. https://iiif.archive.org/iiif/usgs_tx/3/collection.json ➜ https://iiif.archive.org/iiif/usgs_tx/collection.json
