Subject: message_spec: fix test to pass under ruby3.1

For some reason, the test is failing like this:

>       expected NoMethodError with "Can not decode an entire message, try calling #decoded on the various fields and body or parts if it is a multipart message.", got #<NoMethodError: Can not decode an entire message, try calling #decoded on the various fields and bod...lling #decoded on the various fields and body or parts if it is a multipart message.'

It seems like the exception message is being duplicated?  However I
cannot reproduce this outside of RSpec even with ruby3.1, or with
ruby3.1 in an upstream-like environment (ruby-standalone + bundle
install).

For now this will stay as a local patch.
