FIX in testnet

[tonycesar]

For call info for utox in testnet and mainnet I prefer call to
https://api.bitcore.io/api/BTC/mainnet/address/1M3r3n8KioSbnyGVmB9iZrsbZF7VFhzZUE/?unspent=true
or
https://api.bitcore.io/api/BTC/testnet/address/mmV25qC6WUUBFbfvz9XoSAde9FHiJpeUh2/?unspent=true

That replace
https://blockchain.info/unspent/?active=1M3r3n8KioSbnyGVmB9iZrsbZF7VFhzZUE&format=json&cors=true

You can see the doc of api of bitcore in
https://github.com/bitpay/bitcore/blob/master/packages/bitcore-node/docs/api-documentation.md
