In conversation starters V2, conversation starters are fetched from
the server using the dedicated ConversationStartersClient.

When the server call fails to result in a set of conversation starters,
we fallback to locally provided conversation starters.

Note that this CL fetches as the UI is becoming visible to maximize
freshness. This logic may need to be changed once we assess latency.
