chore: cleanup expected keepers

[skosito]

Description

Cleaned up unused methods from expected keepers interfaces. Also executed make mocks to remove not needed mocks.

One small inconsistency I noticed is that cosmos-sdk modules keepers (for example bank, account keeper etc) are sometimes added as dependency through NewAppModule, and sometimes when module keeper is initialized with NewXKeeper, not sure if there is some particular reason for this, but i tried to clean that up too.

Closes: #1716
