 steps to reproduce:
 1. install new wordpress instance
 2. create a category `test`
 3. go to its url http://example.com/category/test/
 (i also tried /category/test (without closing slash))

 expected result:\\
 http status 200, "no items found" message\\
 NOTHING FOUND It seems we can’t find what you’re looking for. Perhaps
 searching can help.

 actual result:\\
 http status 404, "page not found" message\\
 OOPS! THAT PAGE CAN’T BE FOUND. It looks like nothing was found at this
 location. Maybe try a search?

 even if you continue:
 4. add a post to the category
 5. visit category page again

 -- you'll get the same result.

 workaround:
 6. switch theme to `twenty fifteen`
 7. switch back to `twenty seventeen`
 8. visit category page again

 -- now you get the expected result, the bug won't reproduce anymore

 versions:\\
 PHP Version 5.6.38\\
 Chromium Version 70.0.3538.77 (Official Build) Built on Ubuntu , running
 on Ubuntu 18.10 (64-bit)
