Yogev Ben David 1b0fb9bead iOS: Fix refreshControl layouting (#28236)
Summary:
In `react-native-navigation` we allow the usage of native iOS navigationBar **largeTitle** which cause the title to "jump" when pulling to refresh.
We found that the layout calculations of the refreshControl element mess up the system behaviour.

## Changelog
