Fix mobile conversation launch resetting to homepage

Remove the useEffect on selectedConversation.id that race-conditions
with handleQuestionSubmit — it fetches the (still-empty) conversation
and wipes messages, sending the user back to the empty state. Refresh
conversation list after streaming completes instead to pick up the
auto-generated title.
