Fixes crash with: Tried to get frame for out of range index -1 [scrollToBottom (scrollToEnd of list with inverted option) only if messages available/loaded]

[fahad86]

Without this fix we end-up having
Tried to get frame for out of range index -1 error thrown from the underlying FlatList

This is currently causing a lot of crashes on Production for us. The crashes happen when we try to navigate to the chat window directly from push notifications

@fahad86 maybe i'm missing something but i have this error when i'm trying to build :
src/GiftedChat.tsx:666:25 - error TS2339: Property 'data' does not exist on type 'Readonly<GiftedChatProps<TMessage>> & Readonly<{ children?: ReactNode; }>'.

I guess the problem you mentioned would happen when there are no properties added to the tag?

Let me add some null checks.

I think with the refactoring for the latest version, empty messages handling has already been implemented in a different place. This PR should however still be valid for versions < 2.1.0

I've just checked, i'm still having the issue in prod with react-native-gifted-chat 2.1.0
"Invariant Violation Tried to get frame for out of range index -1"
