## Issue
Users are annoyed with the constant reset of the 'channel' setting in the Publish page.
## Changes
1. Revert the previous attempt in ff7b4092. The `usePersistedState` method is bad, as it will clash with the Redux value.
2. Implemented the persistence in Redux -- requires "https://github.com/lbryio/lbry-redux/pull/347".
