Remove print_r

I was getting printed output, which isn't what I wanted.

What I got:
```
(
    [Customer] => Array
        (
            [Name] => Olof Johnsson
        )

)
[{"Customer":{"@url":"https:\/\/api.fortnox.se\/3\/customers\/15","Address1":null,"Address2":null,"City":null,"Country":null,"Comments":null,"Currency":"SEK","CostCenter":null,"CountryCode":null,"CustomerNumber":"15","DefaultDeliveryTypes":{"Invoice":"PRINT","Order":"PRINT","Offer":"PRINT"},"DefaultTemplates":{"Order":"DEFAULTTEMPLATE","Offer":"DEFAULTTEMPLATE","Invoice":"DEFAULTTEMPLATE","CashInvoice":"DEFAULTTEMPLATE"},"DeliveryAddress1":null,"DeliveryAddress2":null,"DeliveryCity":null,"DeliveryCountry":null,"DeliveryCountryCode":null,"DeliveryFax":null,"DeliveryName":null,"DeliveryPhone1":null,"DeliveryPhone2":null,"DeliveryZipCode":null,"Email":"","EmailInvoice":"","EmailInvoiceBCC":"","EmailInvoiceCC":"","EmailOffer":"","EmailOfferBCC":"","EmailOfferCC":"","EmailOrder":"","EmailOrderBCC":"","EmailOrderCC":"","Fax":null,"InvoiceAdministrationFee":null,"InvoiceDiscount":null,"InvoiceFreight":null,"InvoiceRemark":"","Name":"Olof Johnsson","OrganisationNumber":"","OurReference":"","Phone1":null,"Phone2":null,"PriceList":"A","Project":"","SalesAccount":null,"ShowPriceVATIncluded":false,"TermsOfDelivery":"","TermsOfPayment":"","Type":"COMPANY","VATNumber":"","VATType":"SEVAT","VisitingAddress":null,"VisitingCity":null,"VisitingCountry":null,"VisitingCountryCode":null,"VisitingZipCode":null,"WayOfDelivery":"","WWW":"","YourReference":"","ZipCode":null}}]
