iOS 可能出现 attempt to insert nil object from objects[2] 异常

你的运行环境

• 插件版本: 2.9.0
• react-native 版本：0.63.4

期望效果

iOS 端正常运行

实际效果

iOS 端部分情况出现闪退，非必现，猜测是 RCTJPushModule.m 里 getAlias 出现 iAlias 为空赋值给 NSDictionary *data 导致报错：
-[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[2]

重现步骤

1. 启动 App
2. 调用 JPush.init(params)
3. 调用 RN 端 JPush.queryAlias(params)

Start in ios/RCTJPushModule/RCTJPushModule.m at getAlias:, where the issue identifies iAlias being used to build the response dictionary. Reproduce the sequence JPush.init(params) followed by the React Native JPush.queryAlias(params) call, then verify that an unset alias no longer causes the iOS crash.
