FIX: Handle nil values in DistributedCache#defer_get_set (stable) ( #15980 )
...
Themes often cache `nil` values in a DistributedCache. This bug meant that we were re-calculating some values on every request, AND triggering message-bus publishing on every request.
This fix should provide a significant performance improvement for busy sites.

PERF: Defer setting of distributed cache in performance critical paths.
...
Setting a key/value pair in DistributedCache involves waiting on the
write to Redis to finish. In most cases, we don't need to wait on the
setting of the cache to finish. We just need to take our return value
and move on.
