Register any-of-address flag for gov

[alpe]

Resolves #1078
Fixes the missing flag registration for cli gov

Tested manually with a custom wasmd that has '-X github.com/CosmWasm/wasmd/app.ProposalsEnabled=true' set:

wasmd tx gov submit-proposal wasm-store "$DIR/../../x/wasm/keeper/testdata/hackatom.wasm" \
  --title "testing" --description "Testing" --deposit "1000000000stake" \
  --run-as $(wasmd keys show -a validator) \
  --from validator --gas auto --gas-adjustment=1.5 -y  --chain-id=testing --node=http://localhost:26657 -b block -o json
