ScribbleHub extractor seems to be broke

[fake-name]

Describe the bug
Trying to convert a scribblehub page to epub fails with an error, generating a ~4kb epub file.

Error: Could not find content element for web page 'https://www.scribblehub.com/series/997267/maou-shoujo-magical-chaos/'.
    at chrome-extension://akiljllkbielkidmammnifcnibaigelm/js/Parser.js:501:23
    at async Promise.all (index 0)
    at async ScribblehubParser.fetchWebPages (chrome-extension://akiljllkbielkidmammnifcnibaigelm/js/Parser.js:470:17)

To Reproduce
Steps to reproduce the behavior:

1. Go to a series page 'https://www.scribblehub.com/series/997267/maou-shoujo-magical-chaos/'
2. Try to save as epub
3. If you include the info page (the first page the chapter list extractor finds), that page fails to extract, generating the above exception.

Expected behavior
Previously, this stuck the series info page as the first "chapter" in the book, which was super handy.

Additional context

I think this can be fixed as easily as changing the content selector to div.fic_row, div#chp_raw.

Ok, I managed to load the unpacked extension and can confirm that change resolves the issue. See #1374

Test versions for Firefox and Chrome have been uploaded to https://drive.google.com/drive/folders/1B_X2WcsaI_eg9yA-5bHJb8VeTZGKExl8?usp=sharing.

Test version for chrome at least seems to be working.

OTOH, scribble hub seem to have ALSO changed their markup, so the chapter extraction is no longer picking up the series page, rendering the whole change moot. so ¯\_ (ツ)_/¯.

Ugh.

Never mind, it turns out it was only triggering the code-path in question if in you had the Add Page with Chapters to Chapters List option checked. It is indeed fixed.
