Curation filter on author patterns page returns a 404 #706
Description
Describe the bug
By applying Curation filter on author patterns page return a 404 HTTP status code.
To Reproduce
- Go to a author patterns page (e.g: https://wordpress.org/patterns/author/colorful-tones/, https://wordpress.org/patterns/author/deepakrohilla/).
- Select Curated filter and press Apply.
- A 404 page is returned.
Expected behavior
A result page with HTTP 200 and message like "No results found" IMHO could be more appropriate.
PS: If it doesn't make sense to apply this filter to community authors, then it might be disabled/hidden at all on that case.
