Won't download Mangadex chapters anymore - mattributes["title"]["en"]

[fsktom]

Hi. I tried downloading a chapter from mangadex, but it returned an error message (which it never did before btw) - maybe mangadex changed something.

$ gallery-dl --verbose https://mangadex.org/chapter/648e7282-8721-4f70-ac2a-4010bf2ed33e

This was already fixed in commit ddd175d. It only happens for manga without English title.
