PLAYNEXT-1277 Remove most searched shows

[mutaben]

Description

The legacy Social View is being shutdown, and some calls won't have a successor.

Most searched is one of them, that's why everything associated with it needs to be removed.

Although I'm fairly certain nothing would break and it just wouldn't show up when returning nothing, it's still good ro remove clutter from code.

I think this PR is not needed since the "most searched shows" call will be fixed later. So no need to remove code now, as long empty list result are hidden in the search.

Closing pull request since the call will be replaced later.

The current behavior is to ignore the section anyway if the result is empty, so it should work without doing anything.
