feat(match2): always populate game and match dates

[Rathoz]

Summary

Resolves #5222

Depends on #5210, #5215, #5207 (this should also fix the golden warnings)

Ensure that both Match and Game Dates are set, by crosspollinating between the two, even when there's only one of the two in the input.

• Match Date will be parsed from the match's input of field date. If the field is not supplied, fallback to use the earliest game's date.
• Game Date will be parsed from the game's input of field date. If the field is not supplied, fallback to use the match's date.
• Auto finished for long live matches has been changed:
  • If there is at least one Game, check that all Games have been "live long enough".
  • If there are no Games, the old logic of that the match has been "live long enough".

How did you test this change?
