/// This test target a bug around minimal splitter in gbpTree and unique index populator. It goes like this:
/// Given a set of updates (value,entityId):
/// - ("A01",1), ("A90",3), ("A9",2)
/// If ("A01",1) and ("A90",3) would cause a split to occur they would produce a minimal splitter ("A9",3).
/// Note that the value in this minimal splitter is equal to our last update ("A9",2).
/// When making insertions with the unique populator we don't compare entityId which would means ("A9",2)
/// ends up to the right of ("A9",3), even though it belongs to the left because of entityId being smaller.
/// At this point the tree is in an inconsistent (key on wrong side of splitter).
///
/// To work around this problem the entityId is only kept in minimal splitter if strictly necessary to divide
/// left from right. This means the minimal splitter between ("A01",1) and ("A90",3) is ("A9",-1) and ("A9",2)
/// will correctly be placed on the right side of this splitter.
///
/// To trigger this scenario this test first insert a bunch of values that are all unique and that will cause a
/// split to happen. This is the firstBatch.
/// The second batch are constructed so that at least one of them will have a value equal to the splitter key
/// constructed during the firstBatch.
/// It's important that the secondBatch has ids that are lower than the first batch to align with example described above.
