To reproduce:

1) Create a CVV with a repository and export it (I used the syncable format, not sure if it matters).
2) Export the repository and library in two other exports.
3) Try to delete the repository from its details page. After the delete modal pops up, delete it, and it will fail. I believe in the finalize step.

The error will complain about library_instances_inverse.

Normal, non-generated content views do work with forced repo deletion.
