Never show no results in discovery "For You" section
Regular Discovery
If a user visits regular Discovery and has no saved tags, copy web logic (screenshot).
Minds+ Discovery
If a user visits Minds+ Discovery, they should see all of the top Minds+ content as if they are in Minds+, but whenever they attempt to open the content, we should prompt then to Upgrade to Minds+.
Currently there is another bug where Minds+ discovery is pulling regular content upon refresh. See #2417 (closed)
