Clean unused / commented code out of plugin.

[angelleye]

The Sucuri service is false flagging our plugin as a phishing vulnerability. I reached out to them about this and they said it's actually code that we have commented that is causing the problem.

The file is: https://github.com/angelleye/paypal-woocommerce/blob/release/classes/wc-gateway-paypal-pro-angelleye.php

He didn't tell me exactly which line caused it, but we just need to make sure and clean out anything we are no longer using. No reason to leave it behind commented out.
