db/utils: decoded_headers will be passed str not bytes

I had made the assumption early on that this would get bytes, but when I
added `assert isinstance(header, bytes)` alot would crash on startup,
changing `bytes` to `str` fixed that. I noticed this when trying to fix
the warning generated in the logging call.
