Condition to Bson fix

[WesleyEdwards]

The ListAllElements was having issues with a list of an object.
Added a test to account for this case and changes to ListAllElements and Not Bson converters

For mongo filters, $nor is a "Top-level logical query operator", meaning that it cannot be nested directly under a field or an $elemMatch.

Previously, Condition.Not always used $nor.
This is invalid, because $elemMatch expects a field condition instead of a top-level query operator.

{
  list: {
    $not: {
      $elemMatch: {
        $nor: [
          { $lt: 4 }
        ]
      }
    }
  }
}

But this is valid:

{
  list: {
    $not: {
      $elemMatch: {
        $not: {
           $lt: 4
            }
        ]
      }
    }
  }
}

But $nor is still necessary when wrapping field conditions and other logical operators (like 'and' and 'or')
i.e. { "$nor": [ { "subField": 1 } ] })

So I changed the 'Not' Condition -> Bson to account for that. I also made it so ListAllElements uses the Not conversion logic because it would run into the same problem
