[Bug]: genesis migration to v0.50 fails

[alpe]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

There is no genesis migration for v0.50 [registered](see https://github.com/cosmos/cosmos-sdk/blob/release/v0.50.x/x/genutil/client/cli/migrate.go#L25-L28).

Cosmos SDK Version

v0.50

How to reproduce?

simd genesis migrate v0.50 <filename> (I have tested with wasmd but should be the same with simd)

There is no genesis breaking change in v0.50, this is why this isn't added there.

Not sure about the solution but a genesis export/import fails with:
panic: failed to load latest version: version of store circuit mismatch root store's version; expected 3 got 0; new stores should be added using StoreUpgrades

These are the steps to reproduce the issue:

# setup with 47
./simd_v0.47.5 init --chain-id=my-chain val1 --home=$(pwd)/tmp_18021
./simd_v0.47.5 keys add validator --home=$(pwd)/tmp_18021
./simd_v0.47.5 genesis add-genesis-account validator "1000000000stake" --home=$(pwd)/tmp_18021
./simd_v0.47.5 genesis gentx validator "250000000stake" --chain-id=my-chain --amount="250000000stake" --home=$(pwd)/tmp_18021
./simd_v0.47.5 genesis collect-gentxs --home=$(pwd)/tmp_18021

# start and produce some blocks
./simd_v0.47.5 start --halt-height=3 --home=$(pwd)/tmp_18021

# export
./simd_v0.47.5 export --output-document=$(pwd)/genesis_exp47.json --home=$(pwd)/tmp_18021

# start from genesis import state

Have your v0.50 chain the same modules as your v0.47.5 chain? Our simapp in v0.50 added the circuit module, so in this case, this makes sense it fails.
