Summary:
# What's the problem?
`RCTSurfacePresenter._scheduler` is deallocated in `RCTSurfacePresenter.handleBridgeWillReloadNotification`.
It shouldn't be used before `RCTSurfacePresenter.handleJavaScriptDidLoadNotification` is called because that's when new `RCTSurfacePresenter._batchedBridge` is created, scheduler depends on this new `RCTSurfacePresenter._batchedBridge`.
But it is, it means that it is created with the old bridge, this means that it gets deallocated right away.
First access point of old bridge is in `RCTSurfacePresenter.setMinimumSize`.
# What's the fix?
Make sure surface has correct stage before calling layout methods.
The other idea was to return early in `RCTSurfacePresenter.setMinimumSize` in case bridge isn't setup.
# Problems?
1. Following error still appears after reload
{F176556210}
2. There is a white space for a while. By white space a mean the screen stays white for a short period of time before displaying content.
