Remove Error noise from Clojure MathJSON representation when equation is valid

[jefffriesen]

I started typing into a Mathfield and made a syntax mistake. Specifically, I didn't realize the parens autocompleted, so I wrote:

1+x+cos()y

Instead of

1+x+cos(y)

I went back and fixed it. But the Clojure representation included a lot of Errors in it even though rendered Tex looked fine. I refreshed the page, typed it in correctly the first time, and didn't get all of the Error cruft. See screenshots.

Typed without errors

Thank you for this! I filed a ticket with the mathlive repo (linked above), so we should reach paren-shifting nirvana soon. What we really need is paredit in the browser :)
