Fail to add Referee appointments with `edit_match` view related to live streaming feature

[goodtune]

We have a regression - when trying to perform referee appointments on a match, there are issues in two states.

Firstly, when the Season is set as live_stream=False and has no YouTube configuration, the videos field is shown on the edit_match form; but it is required. Trying to add referees will fail at the UI because the requiredness of the form field will block the submission.

The second is when you turn live_stream=True; while the form will adapt and stop showing the videos field, it throws an exception on submission:

During handling of the above exception (Redirect matching query does not exist.), another exception occurred:

Some useful example data to try and reproduce in a test case:

Exception Type: TypeError at /admin/fixja/competition/1/seasons/53/division/232/stage/472/match/7616/
Exception Value: Missing required parameter "id"
Raised during: tournamentcontrol.competition.admin.edit_match

label = ''
round = '1'
date = '15/07/2024'
include_in_ladder = '1'
live_stream = '0'
live_stream_thumbnail = ''

This is for the second failure mode.

Curiously, there were multiple referees added in the UI - not sure why the data shows referees = '523' (i.e. a single entry)?
