Point to R.id.information, not R.id.text

Although the `textView` in `DonateViewHolder is currently not used, it was
pointing to an id which was not in the layout. This has been fixed in case
future devs choose to use this text view. Alternatively, we could remove it
completely if we don't think it is going to be used in this upcoming UI work.
