Virtual Category "Labels" disappear when viewing only unread articles

[Niehztog]

Tiny Tiny RSS supports article labels. Every article can have a label assigned. The labels will appear as "virtual categories" in Tiny Tiny RSS which contains all assigned articles. This is working well in Tiny Tiny RSS Webapplication. TTRSS-Reader however only displays the Label's "virtual category" when "show all articles" is activated and not when "show only unread articles" is active, even though when the label contains unread articles.

Expected behaviour:

• When a label contains unread articles, it should appear on the main screen, no matter if "show only unread articles" or "show only read articles" is selected.
• When a label contains only read articles, it should appear on the main screen only when "show all articles" is selected, and not when "showe only unread articles" is selected

Screenshots which illustrate the problem

show all articles mode => label appears

show only unread articles mode => label disappears

...while the label contained unread articles

besides, when a label contains unread articles, its missing the unread-counter next to it
