Default commands have unpruned params

[GantMan]

As violent delights have violent ends, so do default commands have unpruned params
-- Dolores

running ignite add ui gives parameters.first the value of "default"

This looks like some leakage.

👙 Bikini Bonus:
Would be helpful to have parameters.last - which is how I plan on fixing this for futureproof ways. But I'm not a fan of that method.

Ya, I agree, something seems off about parameters.

parameters gets rewritten because i'm trying to target the plugin/command.

I'm up for changing this.

I think what's bothering me about this is its confusing arguments (things that exist on the command line) with arguments (things that get fed into a command). I think we can probably clear this up with a conversation.

If we do change this, maybe we should use a different property to stay backwards compatible? Maybe that's a horrible idea but I have parameters.second strewn all over my code.

This has completely reworked in 2.0
