Fix crash during reload on Marketplace Home

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.
