If a marriage dialogue patch doesn't apply until a subsequent day, it's not applied when the conditions match (see sample log).

Repro steps:

1. Add this save file and this content pack.
2. Go to bed in-game.
3. patch summary shows the dialogue is loaded and conditions match, but not applied.

That's difficult to fix. The marriage dialogue is set in npc.dayUpdate and npc.marriageDuties from the middle of _newDayAfterFade, so Content Patcher can't just update its context before it's called or invoke a reload-dialogue method. Not sure how to fix this cleanly yet (without just reimplementing the game logic).

Fixed via Stardew Valley 1.4 and the upcoming SMAPI 3.2.
