this is the last one to get parity with current modeling, I think?? I'm gonna add one more feature though: removing no-longer-used assets from the item
This is mostly because I want to chain the rels after both items and assets save, and I want to be able to specify that stuff a bit more precisely, rather than the like, layers-of-awaits we were building up.
We download the schema from prod, and omit real data, but I didn't notice that we were still pulling the metadata of the auto increment counter for IDs! Now, we scrub that from the schema file we save.
Boom, now we can also run a clean MySQL test db on each test that wants it :)
the test I wrote as a sample is currently marked `it.skip` because it's not passing yet!
