refactor: make use of newly introduce SaveCommunityToken() API

As discussed in status-im/status-go#3798, there
was a need to separate the logic in `AddCommunityToken()` into two API.

This commit adjust the client to these changes such that:

1. After community token deployment tx was sent, we create
   a `CommunityToken` and add it to the database for tracking purposes
2. Once the tx is mined or dropped, we add the community token to the
   community description and publish it, or we update the deployment
   state in the database

Needs: status-im/status-go#3798
