⚠️ Fixes for Ruby Warnings

[amatsuda]

Here are fixes for some Ruby warnings with the 2.0.1 gem.

Thank you for looking into this!

Ugh, why did I miss the comment at the top of the file I was editing... I guess I'm done!

Now client.rb needs regenerating. I'm happy to do it myself, can you please change your branch name to something easier to work with in the shell?

[amatsuda]

I did run ./generate.rb and included the related change for client.rb in the relevant commit.

Besides that, I see a chunk of diff like this in the generated code:

diff --git a/lib/amq/protocol/client.rb b/lib/amq/protocol/client.rb

       # THIS DECODES ONLY FLAGS

I didn't include that in this PR because this reproduces when I run the generator in master, so I'm sure this is unrelated to my changes here.

OK, I will take a look. Thank you.

@amatsuda thank you. Indeed the fix in #56 wasn't properly applied to the pytemplate file.

A minor comment on the branch name if I may. It's certainly witty to use a single warning sign emoji in a branch that fixes warnings but it was a bit frustrating to work with in the terminal.

I will release a 2.1.0 later today or tomorrow. Thanks again.

@michaelklishin Thank you! And I'm so sorry about the branch name...
