Remove extra closing quote from error message

[G-Rath]

I also removed the dot because it felt like an odd duck to me given the error continues down, i.e.

Error: No rules found with --split-by property "meta.docs.requiresTypeChecking".

Test for this needs to be updated.

All our other exceptions end with a period which I think is helpful for knowing where the sentence ends. I would actually like to remove the stack trace from what the user sees, so the error won't be continuing after the message.

Thanks!
