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 7ab2b3b690ef6447cfd16842af3008817f8e77f7.

Removes this message.

Fixes #21417
