Subject: [PATCH] fix[MockJS]: fix bug with withCredentials after using mockjs 
 (#1194)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* 修复 Mock 导致请求丢失 Cookie 的问题

修复 Mock 导致 Cookie 丢失的问题，只有在 XHR.open() 周期时，自定义的 withCredentials 会被挂载，此时检查是否是未被拦截的 xhr，并挂载自定义的 withCredentials ，无则默认为 false
