Remove allowBackup from manifest

This resolves merge manifest errors which occur when a project
integrating the library has `allowBackup` set to false.

The existing behaviour could be overridden with:

```
<application
        android:allowBackup="false"
        tools:replace="android:allowBackup"
....
```

But not having the declaration at all since the library doesn't
specifically use it is a better default.
