A0-4053: Remove without-storage-info macro where possible (#1617)

# Description

Complying with paritytech/polkadot-sdk#323 in
two pallets (out of five). The other (`aleph`, `committee_management`
and `elections`) contain vectors, but they are sudo-controlled, so we
should be kinda safe (although we might want to come up with some size
bounds there at some point).

## Type of change

- Bug fix (non-breaking change which fixes an issue)
