File objects get attribute `content-type` which must be accessed through `getattr`

[dbosk]

Describe the bug

File objects get attribute content-type which must be accessed through getattr. All other attributes can be accessed by some_file.attribute, but due to the - that doesn't work for the content-type attribute.

To Reproduce

Steps to reproduce the behavior:

Get an attachment from a submission (submission.attachments). Then one must use getattr(attachment, "content-type") to get the content type. But one can access attachment.filename by dot notation.

Expected behavior

I would expect the content-type attribute to be translated to content_type.

Additional context

Probably adding a translation of - to _ in CanvasObject.set_attributes should suffice. Not sure if this would break anything.

Can I look into this?

#650 I attempted to solve this issue by editing CanvasObject.set_attributes and adding some test cases. Please let me know if there is anything I need to change.
