Only set originalArgs if they're not undefined

[msutkowski]

Fixes #1709.

I believe we can just skip setting this property in the substate when it's undefined. I double-checked all of the invalidation behavior and this appears to be a non-issue.

For a user that uses originalArgs, there is no difference in the check they'd have to use for this anyways?

I think this should do just fine. I'll give it another look in the evening just to be double sure.
