Summary:
ENG-5307 : Start performing message store ops on worker
ENG-5806 : Start performing message store threads ops on worker
Part of ENG-3490 : Migrate stores to SQLite on web

Start persting messageStore on web, inside of sqlite db.

Depends on D11538

Test Plan:

• Open web app, check that the "migration" runs and:
  • Ops with messageStore from keyserver are dispatched to the db
  • Redux contains the data
• Reload the web app and check that:
  • Keyserver doesn't send the message info
  • Message info is loaded from db and dispatched in setInitialReduxState action
• Play around with the app check if there are any errors
