fix(backup): Avoid notification flood in Android when uploading

We must show a notification in Android because it is a background
upload but react-native-background-upload does not allow easily to do
1 notification for multiple files. It is 1 notification for 1 file.
So we add the autoClear: true property which remove the notification
when an upload is completed. It is a good workaround to avoid
notification flood.
