Update Client.js (#3286)

fix: resolved issue with 'onPollVoteEvent' binding after logout

- Fixed error: 'Failed to add page binding with name onPollVoteEvent: window["onPollVoteEvent"] already exists!'
- The error occurred after logging out and attempting to reconnect.
- Connection would get stuck in 'authenticated' state and never reach 'ready'.
