The comment here seems to be wrong, as far as I can tell, this
case can only happen when viewing a diff with no changes
(`data.result === 'nochanges'`) or saving an edit and getting
a captcha (`data.result === 'error'`).
The handling here, added in the recent refactor
b0f4b4c94e, causes both of these
cases to behave wrong (displaying the error message, instead of
empty diff / captcha form).

* Add a postWikitext method and split out postContent
from postHtml
* Move saveSuccess handling into postContent promise
* Connect promise directly to saveComplete instead
* Pass whole response.visualeditoredit object, instead
of splitting into variadic arguments for saveComplete.
* [DEPRECATION] Make serialize return the postHtml promise
and deprecate passing a callback.
