## Description

Closes: #8961 

SDK allows InitGenesis to return with an empty validator set. In practice, the error for an empty validator set gets thrown in tendermint. To fix this,

* Add non-empty validator set check to the `mm.InitGenesis` function. This will break `simapp.Setup` because it relies on an empty validator set [#comment](https://github.com/cosmos/cosmos-sdk/pull/8909#issuecomment-804850834).
* Update `simapp.Setup` to use a single validator.
* Fix failing tests (Most of them are keeper tests).

<!-- Add a description of the changes that this PR introduces and the files that
are the most critical to review. -->
