Fix visual issues with saving fields during publish.
Review Request #1102 — Created Feb. 26, 2018 and updated
When publishing a draft review request, we go through and save all open inlineEditors. This was using the "save" method instead of "submit", which caused a regression in multi-line fields that use CodeMirror. The result of this is that the fields would disappear entirely. Switching to "submit" makes it show the rendered version properly. Testing done: Made some changes to "description" and "testing done", and then tried to publish my draft. Saw that the fields didn't disappear. Reviewed at https://reviews.reviewboard.org/r/6100/
