[IMP] website_event_track_live: hide "YouTube replay" if no YouTube URL configured

This commit slightly adapts the invisible attrs domain of the is_youtube_replay
field to account for empty OR False youtube_video_url values.

So that the youtube replay field is always hidden if no youtube URL is
configured.

Side note: The web client should probably consider empty as a Falsy value so
that we can write simpler attrs domain based on empty/False Char values.

We also took this opportunity to tweak some youtube field labels.
