Fix transaction comment bug

Summary: form.reset() resets a form to whatever values were present when the form was loaded into the DOM. Instead, grab all the pertinent form bits and set there values to "clear". I don't think there's too much utility in putting this somewhere more general, but it could be something like DOM.clearForm(form) or something. Fixes T3629.

Test Plan:
repro'd original issue

 - open legalpad doc (or your favorite application transaction powered app)
 - type in a comment but do not submit (you are creating a draft) e.g. "foo"
 - reload page and note comment appears e.g. "foo"
 - change comment e.g. "foobar"
 - submit comment
 - BUG - after submission, the comment reverts to the comment at initial page load e.g. "foo"

then after this patch, I can't repro it anymore with these steps - the comment is correctly blank

 NOTE: this will need to be tested with more complicated forms.
