Sketcher: remove "SecondIcon" logs on constraint icon hover

Hovering the cursor over constraint icons sometimes logs "SecondIcon"
messages to the report view, doing so for every cursor move event.
This message isn't useful outside of a development context and in fact
is a leftover from 11c76c998e.

Removes this message.

Fixes #21417
