ArticleTargetSaver: Fix handling for data.result !== 'success'

Browse source 
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).
