fix: message history issues

- Display loading indicator on login when mailserver messages are requested
- Fix bug where the mailserver that's selected as soon as you login is disconnected while being still in the process of connecting instead of waiting until 10s have passed to try connecting to a different mailserver
- Use status-go version that fixes an issue fetching mailserver messages when more than 999 messages are being verified if they're in the cache
