Changing per-file download priorities using web client currently broken on master

[TheWug]

Attempting to change the priorities of a downloading file cause the buttons to become "stuck down" as shown. When the page is refreshed, they remain at their previous values. A little bit of chrome debugging indicates that, as far as i can tell, the correct set-torrent RPC calls are being generated, and those calls is succeeding, but for some reason the priority values are not sticking.

Running a torrent for a short period of time confirms that the priority changes are being ignored, and not applied invisibly.

Probably broken in the #1476 rewrite.

@TheWug, is this still broken for you?

Looks like it's still broken as of 16ec15d.

Fixed by #4610.
