Disambiguate actions correctly when they are overloaded by Enum types

Enum types by default are FromUri as it has a TypeConverter from string.

we should make sure the logic finding the simple type are the same between model binding and action selection.

Just ran into this as well. If you take the default WebAPI project template and replace the optional int id parameter on the get methods:

...
    // GET api/values
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    //// GET api/values/5
    public string GetBaz(SomeEnum id)
    {
        return "value";
    }
...

Then WebAPI will no longer be able to disambiguate between these 2 methods and throw an exception saying there are 2 action methods matching the request.
