Fix for CustomDeclarationOrderCheck_issue#190 (setters treating)

Due to this fix, Check treats setters in narrow cases, such as: 
public void setWorkMode(String workMode) {
   this.workMode = WorkMode.valueOf(workMode);
}
public void setUserCache(UserCache userCache) {
   super.setUserCache(userCache);
}
public void setY(Integer y) { // setter
   this.y = Integer.parseInt(y + "");
}

Currently, if there's assignment with method call and in case if there's calling setter from the super class
