Don't mock ErrorDecoder in ConjureBodySerDeTest

[mpritham]

Before this PR

When testing ConjureBodySerDe, we mock the function calls to ErrorEncoder. When implementing #2443, I introduce a replacement for ErrorDecoder. I would like to be able to validate that we don't have regressions in the current error handling logic and not mocking ErrorDecoder will help: I can validate that the logic in ErrorDecoder is still valid with my changes in #2443 where I replace logic in ErrorDecoder with calls to a delegate EndpointErrorDecoder.

What do the change types mean?

• feature: A new feature of the service.
• improvement: An incremental improvement in the functionality or operation of the service.
• fix: Remedies the incorrect behaviour of a component of the service in a backwards-compatible way.
• break: Has the potential to break consumers of this service's API, inclusive of both Palantir services
  and external consumers of the service's API (e.g. customer-written software or integrations).
• deprecation: Advertises the intention to remove service functionality without any change to the
  operation of the service itself.
• manualTask: Requires the possibility of manual intervention (running a script, eyeballing configuration,
  performing database surgery, ...) at the time of upgrade for it to succeed.
• migration: A fully automatic upgrade migration task with no engineer input required.

Note: only one type should be chosen.

How are new versions calculated?

• ❗The break and manual task changelog types will result in a major release!
• 🐛 The fix changelog type will result in a minor release in most cases, and a patch release version for patch branches. This behaviour is configurable in autorelease.
• ✨ All others will result in a minor version release.
