MD5 returned by SQS does not match the calculation on the original request (ruby aws-sdk-core >= 2.3)

Hi srs,

I've worked in a project with the ruby gem Shoryuken, and I got a problem:

It always worked well until I update the gem by bundle update shoryuken, updating the aws-sdk-core too.
Since that, I got the error:

Aws::Errors::ChecksumError:
       MD5 returned by SQS does not match the calculation on the original request. (MD5 calculated by the message atributes: 'ff41d67aace8f6c385e8a5071b828b5c', MD5 checksum returned: '')

The error occurs just version >= 2.3 of aws-sdk. I had no problems with versions up to that.

Looking the backtrace, I found this validation:
https://github.com/aws/aws-sdk-ruby/blob/v2.3.2/aws-sdk-core/lib/aws-sdk-core/plugins/sqs_md5s.rb#L75

Sorry, the same problem of ticket #35

For anyone else looking into this problem, the fix for me (aws-sdk-core 2.7.3) was:

Aws.config[ :verify_checksums ] = false
