Summary:Currently, an empty `<ScrollView />` on iOS always throws the warning "Sticky header index 0 was outside the range {0, 0}".
This is because the error-reporting code relies on the assumption that `stickyHeaderIndices` exists, and when it doesn't the error check thinks there's an index when there really isn't.
Note that this only changes error reporting and won't affect apps out of debug mode.
**Test plan**
I created a sample app and included an empty `<ScrollView />`. Without this change the "Sticky header..." warning was displayed on every run through. With this change implemented, the warning went away.
