What happended?

I'm implementing a custom tax provider. When returning the tax lines via the getTaxLines method, the metadata is not saved to the created tax lines in the database.

return [
  {
    rate_id: "rate_id",
    rate: 4.50,
    name: "tax_name",
    code: "tax_code",
    line_item_id: item.line_item.id,
    provider_id: this.getIdentifier(),
    metadata: {
      foo: "bar"
    }
  },
  ...
]

Expected behavior

The metadata values should be saved to the created tax lines in cart_line_item_tax_line.

Actual behavior

The metadata values are not saved to the created tax lines in cart_line_item_tax_line.
