Null value as default gets 01/01/1970 on field

[cywiretech]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-paper-dates@0.8.7 for the project I'm working on.

Hi! I found this issue using expo and running expo web on chromium. If i use the null value for the start date value, i see 01/01/1970 instead of the empty field. This patch resolve the issue, i hope it is right

Here is the diff that solved my problem:

diff --git a/node_modules/react-native-paper-dates/lib/module/Date/inputUtils.js b/node_modules/react-native-paper-dates/lib/module/Date/inputUtils.js

   const onChangeText = date => {
