Previously it was failing and not recording. Also, the
`BUNDLER_SPEC_FORCE_RECORD` environment variable was forcing every
request to be recorded, including duplicated requests to the same
endpoint. That meant the recorded `versions` file would be incorrect
because it would contain the result of the last request, which would be
`304 NOT MODIFIED`.
So, to rerecord, delete cassettes and let them be recorded when needed.
