Introduce UnwrapError trait to simplify error testing
For testing purposes it is beneficial to be able to check for expected errors with the least amount of boiler plate code possible. This change attempts to be a first step into this direction. It introduces a test-only trait that can be used to directly unwrap a specific error from a Result<T, crate::error::Error>.
