[Bug]: Simulations fail because validator set is empty in the genesis before chain init

[pinosu]

Summary of Bug

For certain seeds it happens that simulations panic because validator set is empty in the genesis before chain init.
This happens because initially_bonded_validators sometimes is 0 and this scenario should not be possible.
Logs example:

Selected randomly generated parameters for simulated genesis:
{
  stake_per_account: "{824639709536}",
  initially_bonded_validators: "0"
}

Version

0.47.3

Steps to Reproduce

In wasmd module it can be reproduced by running:
go test ./app -run TestAppStateDeterminism -Enabled=true -NumBlocks=1 -Genesis= -Verbose=true -Commit=true -Seed=4003615766033486007 -Period=1 -ExportParamsPath /tmp/sim-logs-548063760/sim_params-4003615766033486007.json -ExportStatePath /tmp/sim-logs-548063760/sim_state-4003615766033486007.json -v -timeout 24h

We'll take this into account with the refactored simulator package 👍
