* fix the test for R18 posts, which are now supported
* replace the dead post for the imageMap test with an active one
* fix the ordering of images: it was possible to get the wrong image in
some cases when not using the batch bookmarklet, because of how fanbox
orders imageMap posts
* fix a bug where the sample wasn't properly replaced with the full
size
* rename test file to match the rest of the other files
Prevent age-restricted fanbox posts from raising errors when source data
is fetched. This prevents error messages from being shown to users when
switching to the edit tab on a post.
This will cause uploads of age-restricted posts to fail with an
unrelated error because we either can't find the image url (if we were
given only the html page) or we can't download the image (because we're
not logged in to Fanbox).
