极光推送Jpush的“appKey and masterSecret format is incorrect”问题修复

报错信息：

java.lang.IllegalArgumentException: appKey and masterSecret format is incorrect. They should be 24 size, and be composed with alphabet and numbers. Please confirm that they are coming from JPush Web Portal.

一开始我还以为，复制粘贴出错了，还真是粘贴的时候出错了。

本来应该24个字符的，多了一个空格。
