fix: avoid re-renders inside contact-list for new-chat sheet (#21640)
This change fixes some of the re-rendering issues that occur inside the contact list when creating a new chat. Most important is that we avoid extra re-renders by configuring the flat-list with stable props. And we also avoid re-rendering avatar images each time the avatar component re-renders.
