Queries against in-memory ODataEntities can have type inference issues

[madelson]

Here's a sample which repros the issue:

void Main()
{
    var data = new[] {
        new Dictionary<string, object>{ { "D", 1.1 }, { "I", 1 } },
        new Dictionary<string, object>{ { "D", 4.9 }, { "I", 4 } },
        new Dictionary<string, object>{ { "D", 9.2 }, { "I", 9 } },
    }.Select(kvps => new ODataEntity(kvps))
    .AsQueryable();

    var nameValueCollection = new NameValueCollection();
    nameValueCollection.Add("$format", "json");
    nameValueCollection.Add("$filter", "D gt 5.0");
    //nameValueCollection.Add("$filter", "D gt 5"); // this version fails casting 1.1 to int

    var service = new ODataService();
    var result = service.Execute(data, nameValueCollection);

    result.Dump();
}

A possible fix could be to special-case enumerable queries and handle them in a mode that tries the compiled expression but falls back to doing the same thing with dynamic.
