SearchHistoryMenu: improve scrolling through selection with arrow keys

[Wittmaxi]

Scrolling through the selection of the Search History now correctly starts at the first item and cycles through the boundaries (ie. scrolling down from the last item returns correctly to the first item of the list)

fixes #2139

The hover is now sticky such that the navigation with the arrow keys resumes from the position where the last hover happened. This also meant that some state (the scrol positoin) had to be moved into the entire Search History Menu instead of in the key listener (see comment above).

That way, I could fix the comment about using the adapter for the listener on the fly.

@HeikoKlare if this is fine with you, I will merge by end of day
