database: Update constraints to allow null edit inputs in state DONE

This allows manual uploads to work without needing to fill all the edit fields
with junk.

We also set a constraint on uploader asserting that any videos from claimed onwards have a known uploader.
Again, an exception is made for DONE to allow manual uploads.
