Fix go-generate calling, do more before running tests

Does a couple things:
- `make generate` now infers files that might affect generation.  This should work as long as we keep simple codegen (the server has moved beyond this, sadly).
- `make generate` now forces re-generation regardless of need, because it's a nice workaround for dependency issues like happened in #1373
- `make test` and related targets now go-generate and fmt before running tests.  Slower, but you can't forget to re-generate, and they're slow already so it's probably fine.
