Unable to retrieve dictionary values in nested call to the each helper when the data is a mix of Dictionary and List.

[cjvirtucio87]

Describe the bug

When using data that is a mix of Dictionary and List instances and a template string that uses an #each helper nested inside another #each helper call, the template is unable to retrieve dictionary values inside the nested #each.

Expected behavior:

A template string that has a retrieval attempt of a dictionary value within a nested #each call results in that value being written to the final output.

Test to reproduce

(this is taken from this unit test I've written on a fork):

        [Theory, ClassData(typeof(HandlebarsEnvGenerator))]
        public void NestedEachDictionariesLists(IHandlebars handlebars)
        {
            var source =
                @"
                {{#each this.users}}
                    {{#each friends}}
                        {{emailAddress}}
                    {{/each}}
                {{/each}}
                ";
            var template = handlebars.Compile(source);

            var friends = new List<Dictionary<object, object>>
            {
                new Dictionary<object, object>
                {
                    { "emailAddress", "foobarbaz@baz.com" }
                },
            };
            var users = new List<Dictionary<object, object>>
            {
                new Dictionary<object, object>
                { 
                    { "friends",  friends },
                },
            };
            var data = new Dictionary<object, object>
            {
                { "users",  users },
            };

            Assert.Equal(
                "foobarbaz@baz.com",
                template(data).Trim());
        }

The above test fails with the following output:

Expected: foobarbaz@baz.com
Actual:

Seems to work fine when using arrays:

$ dotnet test Handlebars.Test/Handlebars.Test.csproj --filter 'FullyQualifiedName~HandlebarsDotNet.Test.BasicIntegrationTests.NestedEachDictionariesArrays'
