Don't count solved problems in Overview

At the moment, the Overview page shows the total number of log errors
and warnings, even if they are marked as "resolved". After the patch,
only unresolved errors and warnings are counted.
Test:
Created an error event and a warning event in the log.
The Overview page displays 1 and 1.
Marked them as resolved.
The Overview page displays 0 and 0.
