ScoringClassMapBuilder generated the wrong map

[shenzhaoquan]

1. I defined two entities as shown below
   public static class A {
   public String title;
   public String content;
   }

   public static class B {
   public String title;
   public Integer lengthTitle;
   public String content;
   public Integer lengthContent;
   }

2. Add test case
   @test
   public void testScoringMatchingBug() throws Throwable {
   MapperFactory factory = new DefaultMapperFactory.Builder().classMapBuilderFactory(new ScoringClassMapBuilder.Factory()).build();

    ClassMap<A, B> map = factory.classMap(A.class, B.class).byDefault().toClassMap();
    Map<String, String> mapping = new HashMap<>();
    for (FieldMap f : map.getFieldsMapping()) {
        mapping.put(f.getSource().getExpression(), f.getDestination().getExpression());
    }
   
    /*
     * Check that properties we expect were mapped
     */
    Assert.assertEquals("title", mapping.get("title"));
    Assert.assertEquals("content", mapping.get("content"));
   

   }

3. result
   Unit test failed. Title is incorrectly mapped to lengthTitle and should be mapped to title first, content is the same

4. expect result
   Unit test passed.
