fix(OpenAPI): Add missing reactionsSelf to ChatMessage

[provokateurin]

Psalm probably didn't catch the missing field because the logic for setting it is too complicated and it can't figure out what is happening.

spreed/lib/Controller/ChatController.php

Lines 680 to 694 in 704a072

	// Inject the reactions self into the $messages array
	foreach ($reactionsById as $messageId => $reactions) {
	if (isset($commentIdToIndex[$messageId]) && isset($messages[$commentIdToIndex[$messageId]])) {
	$messages[$commentIdToIndex[$messageId]]['reactionsSelf'] = $reactions;
	}
	// Add the self part also to potential parent elements
	if (isset($parentMap[$messageId])) {
	foreach ($parentMap[$messageId] as $mid) {
	if (isset($messages[$commentIdToIndex[$mid]])) {
	$messages[$commentIdToIndex[$mid]]['parent']['reactionsSelf'] = $reactions;
	}
	}
	}
	}

Makes sense, looking at TS output

@Antreesy do you know why typescript wasn't complaining that a non-existent property of an object was used?
