Remove output of sma_sid, because it doesn't always exist

[msarahan]

I have a SunnyBoy 5.0, and this particular attribute doesn't exist. It is _sid instead for me. Since the traceback isn't all that great for newbies approaching the project, I think it might be better to just leave this part out.

Traceback, for reference:

Traceback (most recent call last):

I'm not sure that's a great example?

Make attributes private so they dont show in the docs. Direct access should not be required.

Then why show direct access in the example?

I'm happy to change this so that it works, I just want the example to be as friendly and useful as possible.

Yeah you are right. We could remove this and add a logger.debug statement in de new_session method of SMA to replace it.

nice, I think that's a good place for it. Thanks!
