Fixing another iOS app extension unsafe API usage in react native

Summary:
Thanks for submitting a PR! Please read these instructions carefully:

- [yes] Explain the **motivation** for making this change.
    Using react-native library inside iOS app extension causes a compile error inside react native stating that usage of UIAlertView is not allowed inside iOS app extension and should use UIAlertController instead.

I am currently in process of upgrading my app from 0.34 to the latest react native ( aka app not in working state). Would appreciate if there is an alternative way for me to test this functionality out.

Just tried to create a new react-native project using "react-native init testproject" and upon running "react-native run-ios", I  hit the following error a
