Remove non-null assertion in ConversationProvider
- Add `createOptionalContext` that is used by `AuthContext` and `ConversationContext` to create a context with a hook
that can be used to retrieve its value and throw an error if it's undefined.
- In `router.tsx`, put `Messenger` inside `ConversationProvider`.
- In `ConversationListItem`, use the conversationId from the `ConversationContext ` instead of the url params.
- Fix bug in `CallInterface` with fullscreen.
- Remove unecessary useEffect dependency in `NotificationManager`.
