Do not crash if generic class has inner class

[if1live]

Example code

using UnityEngine;
using System;
using System.Collections.Generic;
using Vexe.Runtime.Types;

[Serializable]
public class ProiorityList<T> {
    [Serializable]
    public class Pair {
        public T elem;
        public int priority;
    }
    public List<Pair> pairs = new List<Pair>();
}
public class TestScript : BaseBehaviour {
    public ProiorityList<Vector3> proiorityList = new ProiorityList<Vector3>();
}

Description

Somtimes, type.Name doesn't contains ```.
In example code, ...

• type: VFWExamples.ProiorityList`1[UnityEngine.Vector3]
  • type.Name: ProiorityList`1
• type: System.Collections.Generic.List1[VFWExamples.ProiorityList1+Pair[UnityEngine.Vector3]]
  • type.Name: List`1
• type: VFWExamples.ProiorityList`1+Pair[UnityEngine.Vector3]
  • type.Name: Pair

if name doesn't contains ```, IndexOf function return -1. I use it.
