…eject invalid array (mongodb#10)

The Query\Builder::whereBetween() method can be used like this:

whereBetween('date_field', [min, max])
whereBetween('date_field', collect([min, max]))
whereBetween('date_field', CarbonPeriod)

Laravel allows other formats: the $values array is flatten and the builder assumes there are at least 2 elements and ignore the others. It's a design that can lead to misunderstandings. I prefer to raise an exception when we have incorrect values, rather than trying to guess what the developer would like to do.

Support for CarbonPeriod was fixed in Laravel 10: laravel/framework#46720 because the query builder was taking the 1st 2 values of the iterator instead of the start & end dates.

…$not` (mongodb#13)

`Query\Builder::whereNot` was simply ignoring the "not" and breaking the built query.
