[Bug]: Navigating to /game/:gameId as a non-player shows blank screen instead of redirecting to /spectate/:gameId

[itsalaidbacklife]

Bug Summary

If a user navigates to /game/:gameId for a game in which they aren't a player, they should be redirected to /spectate/:gameId but instead they see a blank screen

(e.g. go to https://www.cuttle.cards/game/46882)

Detailed Description

Players play in a game at the route /game/:gameId, and spectators watch at /spectate/:gameId. If a player shares their current link and a different user (not a player in the game) goes there, the non-player user should be neatly redirected to /spectate/:gameId instead of seeing a blank screen:

Current Behavior

Navigating to /game/:gameId as a nonplayer user shows a blank screen

Expected Behavior

User is instead redirected to /spectate/gameId

Steps to Reproduce

1. Join and start a game as users 1 and 2
2. Navigate to /game/:gameId for the gameId of the above game as a third user (not in the game)
3. Third users will now see blank screen
