How can testnet CashAddr addresses be converted back to the old format?

I noticed on the new update of the Bitcoin Cash wallet (BitcoinABC) (for testnet and not sure for mainnet) that it has a weird beginning and address (e.g. bchtest:qrz89sz3r47ndj60xq68xeus0hx9qwlpkuw5pw01de). Is there any way to convert it back to the old format as there are some places that don't support this format yet (like one of the BCH testnet faucets)?
