MyBatis A typo in test method name

Comment From: harawata

Hello, @nothingzhl ,

The typo in the method name should be fixed. The added tests, however, may not increase the coverage because the target code is already covered by other tests. https://mybatis.org/mybatis-3/ja/cobertura/org.apache.ibatis.reflection.property.PropertyCopier.html https://mybatis.org/mybatis-3/ja/cobertura/org.apache.ibatis.reflection.factory.DefaultObjectFactory.html

I have removed the tests and merged the PR. Thank you!
