So boxing T::PalletsOrigin decreases the call size for Authority from 608 bytes to 24 bytes in karura. Not entirely sure why but numbers don't lie

This tests passes, yet in karura runtime the Call size for orml_authority is printed as 608 bytes, this test when printed says call size of 56 bytes. That doesn't really make sense to me

Edit: Nvm, I think I figured it out it probably is because karura sets something different in the runtime than the mock 👍
