Remember scheduled time in the edit-form time picker - attempt

[keikari]

Changes:

• Remember the schduled livestream date in the edit form DateTimePicker
• Remember the scheduled video release date in the edit form DateTimePicker
• If livestream's scheduled time has passed, default to "Anytime" in edit

Not sure if I'm missing something, as I just followed what the TODO comment in old code said. But I didn't found this causing any issues.

• I think we need to replicate the removed logic, i.e. only set the release time if it was isScheduled, or ensure it's only done for specific cases.
  • Because for other forms like unlisted, releaseTime need to be undefined at the beginning of Edit to differentiate whether the user entered something or not (see const PAYLOAD = for reference on userEnteredTs).
• Other than that, it looks good in a glance.

The general thought process was:

• the original values can always be queried from claimToEdit -- single source of truth
• publishData.releaseTime is a UI state that reflects user-entered data. If user did not touch, it remains undefined.
• With that, the payload generator has enough data to construct the SDK payload based on various situations.

Will forget about this for now.

Original reason was, that an user had issues with scheduled stream start time changing randomly. Thought they might have been just confused by the default time in the edit form, but turned out it's not that.
(Don't know what it is exactly, yet)
