* Speed up `waitForMember` if user already in room `waitForMember` waits for a user to join, or be invited, to a room. But if the user is already in the room (ie, we miss the `NewMember` event), we end up timing out after 1500ms. We can save 1.5s here by returning immediately. * fix strict type errors * stfu SonarCloud
