[ticket/11577] Correct over-sized Topic Rows

Fixes a change made in PR 1331 that oversized topic rows.
Icons in topic rows, in Prosilver, are only 27px high, so we do not need
a min-height as high as 40px. Setting it to 30px is more conservative
and reclaims the original height of topic rows from before PR 1331.

[ticket/11437] avoid $start becoming negative when no search results are found

When search returns no results there is no need to go inside the if

which leads to failed assertion.
