Add makeNonTrivial helper in Search

[kunaltyagi]

Instead of modifying multiple call sites with what looks like really weird code, I think it's better to instead add a helper and test it properly.

I don't quite get the name makeNonTrivial?
Except for that, I think its makes good sense to have this login here and the use these calls whenever we are using the radius search and the like?

Ah, yeah, I couldn't think of a shorter name.

Returning the same point as result of search is basically a trivial answer. Ofc the point from the cloud is going to be in there.
So i thought, removePoint, removeSearchPoint, might be confusing, and making the search result non-trivial might not be.

Maybe I overthought? 😅
