address not being updated on keplr account change

[marinhoarthur]

Steps to reproduce:

1. Connect to Keplr
2. Open Keplr and switch account
3. Open our Wallet. The addresses do not match anymore (one from previous account, the other one from the current)

[clockworkgr]

window.addEventListener('keplr_keystorechange', async () => { ...} );

use that but @starport/vuex common/wallet also needs updating as it stores the first instance and needs to be updated (or refactored to always query the currently connected keplr)
