Add punctuation to traverseNeedsParent message.

Is this how it's supposed to read? Saw it here and just thought it should be a => an, but then when I looked it up it seemed like it has a different meaning than I originally read it as.

Error: You must pass a scope and parentPath unless traversing a Program/File got a undefined node

You could write a(n)?

@thejameskyle Thanks. What I mean is, with a or an or a(n) I think it doesn't say what it means. It reads like:

You must pass a scope and parentPath unless traversing a Program/File yielded a $1 node.

But I think it means this:

You must pass a scope and parentPath unless traversing a Program/File. Instead of that you tried to traverse a $1 node without passing scope and parentPath.

Or in other words:

You must pass a scope and parentPath unless traversing a Program/File. Got a $1 node.

(Though maybe ending that with instead would be better.)

Is that correct?

[jamiebuilds]

Yeah it definitely means

You must pass a scope and parentPath unless traversing a Program/File. Instead of that you tried to traverse a $1 node without passing scope and parentPath.

I would just update it to say that

@thejameskyle Thanks for the feedback! Updated it as suggested and merged.
