## Issues
Ad-filtering:
- Filtering was done whether or not ads are injected.
- Constants are repeatedly calculated.
- No short-circuiting in the for-loop.
- No memoization (being called 5-6 times on average due to redux updates, can't avoid that).
Others:
- Potentially passing null claimID to recsys (I think this is the issue that Johnny reported in Slack).
## Changes
- Moved 1-time calculations outside of the function.
- Optimized the filtering function and memoize it.
- Reduce unnecessary props since we are passing the whole `Claim` object already.
- Fix recsys being called when claim is not resolved yet (null claimId).
- Move away from the incorrect `makeSelect*` selectors.
