Effectively the same problem as MBS-8053, but for somewhere else in the code, I assume.

To reproduce:

• Open the release editor, enter a title, select an artist and add at least one track
• Add a URL, select "stream for free" as the type
• Tick the "video" checkbox
• Change the relationship type to "download for free"
• Go to the edit tab and try to submit the edits

Expected behaviour: The "video" attribute is cleared when changing the relationship type to one which doesn't support the attribute.
Actual behaviour: The attribute remains, causing the following ISE when trying to submit:
