Extraneous comments in the code

Suggestion

I was inspecting the packages/contracts/src.ts/index.ts and noticed a commented-out else case: here

Grep-ing the codebase, i found 7 other similar instances of commented-out elses

Would we like to remove these? if so, i can make a quick PR this evening

I think It is something I was planning to add in. When no address was provided, a Geth node used to use the current account, if one was configured, otherwise 0.

But then they changed the default behaviour to always use 0. And specifying 0 did something else (I forget what).

So, I think I commented it out in case it needed to go back in? I would have to look at the changelog from then though. It is a good idea for me to re-examine this behaviour and figure out the correct thing to do in v6.
