Unable to retrieve Transfer Reversal while expanding the transfer object

[davidrichey]

Describe the bug

Unable to retrieve Transfer Reversal while expanding the transfer object as the API Docs state. The expected expand addition to the Stripe Transfer retrieve_reversal raises a NoMethodError.

I noticed the NestedResource retrieve_ does not account for params as the update, delete & list methods do.

To Reproduce

1. Retrieve a transfer reversal with the expand key.

Note: The code snippet is generated from the Stripe Shell

Expected behavior

Retrieves the Transfer Reversal Object with the transfer expanded

Code snippets

Stripe::Transfer.retrieve_reversal(
  'tr_xxx',
  'trr_xxx',
  { expand: ['transfer'] }
)

NoMethodError: undefined method `strip' for ["transfer"]:Array
