One problem after updating from v.1.0.8.18

[OlegNadymov]

In continuation of #759

1. Description

If I use public methods from my target type, I have the following exception:

  System.Linq.Dynamic.Core.Exceptions.ParseException : Methods on type 'User' are not accessible.

Demo:

public class User
{
    public bool TestMethod1()
    {
        return true;
    }
}

I try to parse the expression this way:

var config = new ParsingConfig
{
     CustomTypeProvider = new TestCustomTypeProvider()
};
var exp = "TestMethod1()";
var lambda = DynamicExpressionParser.ParseLambda(config, typeof(User), null, exp);

2. Exception

  System.Linq.Dynamic.Core.Exceptions.ParseException : Methods on type 'User' are not accessible

3. Fiddle or Project

Again, I have done changes in DynamicExpressionParserTests only locally.

4. Any further technical details

It is not working on the release version 1.3.8.
