feat: Re-enable File logger

In #1183 we disabled the new File logger mechanism due to a side effect
with react-native-background-geolocation

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

This commit applies the fix from BeTomorrow/react-native-file-logger#66
(we cannot update the lib as we are still using ReactNative old
architecture)
