[forums] Exclude by CSS selector hides notice completely

Problem

The plugin has a CSS selector option which allows you to whitelist notices matching a CSS selector. This feature worked fine until and including version 1.5.0. Notices which contained a specific selector were not hidden and appeared normally in the dashboard.

In version 1.6.0 these whitelisted notices are completely gone, they are not visible in the ANM tab nor in the WP dashboard. Removing the CSS selector makes the notice appear again in the ANM tab.

to reproduce:

1. Add a few test notices with css selector visible/available
2. include that selector on the white list
3. the notice will be gone completely instead of showing up as normally would on the dashboard.

I was able to reproduce this
