Wrong usage of mappers factory should be able to remove static initializer

还没有人认领这个 Issue。

Why reviewing PR #179 @hduelme pointed out that the Wrong usage of mappers factory does not work (i.e. it does not remove it) with the following code:

```java
@Mapper(componentModel = "spring")
abstract class WrongComponentModelMapper {

static {
Mappers.getMapper(WrongComponentModelMapper.class);
}

Target map(Target source);
}
```

or
```java
@Mapper(config = MyConfig.class, componentModel = "spring")
interface WrongComponentModelMapper {

WrongComponentModelMapper INSTANCE = () -> {
return Mappers.getMapper(WrongComponentModelMapper.class);
};

Target map(Target source);
}
```

We need to see if we can support this.

首先复现 issue 中的静态初始化器和接口字段示例，并跟踪 IntelliJ plugin 当前如何处理 Mappers.getMapper 的使用。查看围绕 PR #179 的讨论以了解背景。完成的标准是确定这些模式是否可以得到支持；如果可以，则通过覆盖两个示例来验证其行为。
