HandlebarsUndefinedBinding thrown for null ExpandoObject values

[andycnguyen]

I've been trying to convert my Handlebars models to ExpandoObjects, as recommended in various issues here. However, I've found that that a HandlebarsUndefinedBinding exception is thrown for null values.

For example, I'd like to make use of templates and models like the following:

{{#if PerhapsNull}}
     It's not null
{{else}}
     It's null
{{/if}}

dynamic data = new ExpandoObject();
data.PerhapsNull = null;

This doesn't work, however, due to the aforementioned exception. I'm aware that I could suppress this exception by setting ThrowOnUnresolvedBindingExpression = false, but I'd rather not do this. (And it seems to me that, in the example I've given, the expression in question should not be considered unresolved.)

I've tested you problem on my fork zjklee/Handlebars.CSharp and it works.
You can try using it until changes are merged to the main repo.
