`toJson` fails to create exactly the same json as the Stripe HTTP API

[decoursin]

Describe the bug

The InvoiceLineItem.getUnitAmountExcludingTax returns a BigDecimal. While the Stripe API HTTP Server returns the unit_amount_excluding_tax as a string.

As a result, when the InvoiceLineItem is serialized using toJson, it returns a completely different format than the Stripe API Http Server. They should be the same.

To Reproduce

1. Create an invoice and 1 invoice item.
2. Serialize that invoice using toJson.
3. View the serialize invoice item, and see that it's serialized as a json number rather than a string.

Expected behavior

Serializing an InvoiceLineItem using toJson is suppose to replicate the Stripe API HTTP server 100% exactly, and it's not doing that.
