1. 当发行为混合分包的时候，uniapp 会调用 initCreateSubpackageApp 方法

2. initCreateSubpackageApp 里调用 parseApp ，并在 onLaunch 时候进行 initBaseInstance

3. initCreateSubpackageApp 里调用 parseApp 后同步执行 `vm.$.ctx.$scope = app;`

4. initBaseInstance 在 onLaunch 会进行 `if (this.$vm && ctx.$scope) {return;}` 阻断，如果通过则执行 `ctx.$hasHook = hasHook;  ctx.$callHook = callHook;`

问题出在 onLaunch 是异步的，导致 4 的流程阻断，没有执行 $callHook 赋值，最终导致 `initAppLifecycle` 中的 `vm.$callHook` 为 undefined
