Describe the bug

This seems to have changed since v1.27.1. This shortcut opens the "next article" not the "next unread article".

After updating FreshRSS and noticing this issue, I went to shortcuts configuration page and noticed the shortcut 'n' was set to "open the next article". I changed it to "open the next unread article" but I see no change in behavior.

To Reproduce

1. Go to 'Shortcuts'
2. Set "Open the next unread article" to 'n'
3. Click on 'Submit'
4. Click "Go back to your RSS Feeds"
5. Select a feed in the left had pane and advance through the articles with 'n'. When it reaches the end of this feed it will advance to the next feed rather than the next feed containing unread articles.

Expected behavior

It should advance to the next unread article in my list of feeds.

FreshRSS version
