remove aws query compatible protocol test

[AndrewFossAWS]

Description of changes:

Essentialy the protocol test is not able to verify fields not defined in the error structure. For example,

@awsQueryError(
    code: "CustomGreetingErrorCode",
    httpResponseCode: 402
)
@error("client")
structure CustomGreetingError {
    Message: String,
}

The httpResponseTests doc states params can only be compatible with the targeted error structure.

The actual error response looks something like this:

{  
  '$fault': 'client',
  '$metadata': {
    httpStatusCode: 402,
    requestId: '19a4103d-121d-5080-ac16-4b9b8ee81639',
    extendedRequestId: undefined,
    cfId: undefined,
    attempts: 1,
    totalRetryDelay: 0
  },
  Type: 'Sender',
  Code: 'CustomGreetingErrorCode',
  Message: "Hi"
}

The protocol test can only verify Message but not other fields like Code.

Note: AwsQueryCompatibleTrait will add Code to the error response.

This commit remove the redundant aws query compatible protocol test.
