Janic Duplessis bb5aede6e3 Fix RefreshControl race condition ...

Summary:
Improved version of #7317.

`setRefreshing` and `setProgressViewOffset` needs to be called after the view has been layed out. Instead of using `post` to do that we update the `refreshing` and `progressViewOffset` values in the first call to `onLayout`.

I also noticed that `progressViewOffset` default value wasn't exactly the same as when not calling `setProgressViewOffset` at all. Tweaked the values to match android defaults.

**Test plan (required)**
Make sure the integration test passes,
In UIExplorer: test RefreshControl with `refreshing = true` initially, test `progressViewOffset`.
