AssetsController upgrade from v30 to v38

### What is this about?

The `AssetsController` is behind by four major versions and needs to be updated.

Because this controller is pretty far behind we expect it will have a number of breaking changes that will need to be dealt with so we haven't combined this with any other controller upgrades.
