PredicateBuilder failed on EF Core 5.x

[mannok]

Steps to reproduce

Please see the codes below

public string[] FindAssets()
{
    string[] result;

    using (var ctx = new StockContext())
    {
        var predicate = PredicateBuilder.New<Asset>().Or(asset => asset.Symbol.Contains("TSLA"));

        result = ctx.Assets.AsExpandable()
        .Where(predicate)
        .Select(z => z.Symbol)
        .ToArray();
    }

    return result;
}

When the code start exec at result = , it throws

Exception: Unhandled expression type: 'Extension'
LinqKit.ExpressionVisitor.Visit(Expression exp)
LinqKit.ExpressionVisitor.VisitExpressionList(ReadOnlyCollection<Expression> original)
LinqKit.ExpressionVisitor.VisitMethodCall(MethodCallExpression m)
LinqKit.ExpressionVisitor.Visit(Expression exp)
LinqKit.Extensions.Expand(Expression expr)
LinqKit.ExpandableQueryProvider<T>.System.Linq.IQueryProvider.CreateQuery<TElement>(Expression expression)

I'll release LinqKit.Microsoft.EntityFrameworkCore version 5.0.0-preview.6 in some time.

(I keep the same preview version as the one which is used by https://www.nuget.org/packages/Microsoft.EntityFrameworkCore/5.0.0-preview.6.20312.4)
