fix: Correctly initialize File logger on iOS

In #1187 we fixed the new File logger initialization on Android as it
would break the react-native-background-geolocation plugin's internal
File logger

This was because react-native-file-logger would reset all log appenders
during initialisation which would prevent native-background-geolocation
to work

This bug was also present in iOS but appeared latter so we did not
notice it and so we did not fix it on initial PR

This commit applies the fix from BeTomorrow/react-native-file-logger#69
(we cannot update the lib as we are still using ReactNative old
architecture)
