Fix double-render of Category Pages when unauthenticated

Browse source 
## Scenario
`selectHasUnclaimedRefereeReward` updated --> `AppRouter` re-render --> `dynamicRoutes` regenerates (re-mounts) list of `DiscoverPage`s

## Fix
I think `selectHasUnclaimedRefereeReward` can be moved elsewhere and would solve the problem, but avoided that since I'm not familiar with rewards enough to do minimal testing.

Memoize the Category Page routes instead.
