Camel-Case-Expansion: alias by Property names, not Pathes

[iilei]

This fixes issue #77
This is a breaking change

@iilei thank you for this contribution ... while this is a breaking change, it feels like it's definitely addressing a bug (and I can't imagine many folks in yargs relying on the old behavior). My temptation is to call it a breaking change in yargs-parser, but to make it a patch in yargs ... then there's a paper trail for folks if it does break anyone, but we don't release a new yargs major.

@bcoe thank you for merging.

I would tend to do the same, for the same reasons. I can imagine it is more likely people have worked around it using aliases rather than relying on it. But that's just my uneducated guess

@iilei this is now available in npm i yargs@next mind taking it for a spin and letting me know if things work alright?

@bcoe here is a code-kata repository / branch on which I verified it works:
