fix useChain

useChain is not correctly picking up all events.

Consider

> ....
> const {address} = useChain("cosmosHub")
> return

If I connect and change accounts, it works.
If I then re-connect and change accounts it does not pick up any account changes, i.e. I change account and the address does not change.

The bug is also in production, i.e. Osmosis frontend.
even forcefully refreshing the component a la
> useEffect(() => () => setRefreshKey(refreshKey + 1), [chain, chainName])

is not working
