feat: re-fetch conversations on opening search-ui [FS-1689]

[V-Gira]

FS-1689 [web] Retry fetching missing conversation metadata when the Search UI is opened

Feature

load missed conversations on opening the search ui

Step by step:

• User A creates a conversation with user B while user B's client is offline
• User A's backend becomes offline
• User B connects to Wire and loadConversations() returns the new conversation as failed
• The failed conversation is saved in user A's conversation state as a missing conversation
• User A's backend comes back online
• When user B clicks on the Contact tab, we refetch the missing conversations, and the new conversation appears in the conversation list

Suggested change

	const updateConversations = async () => {
	await conversationRepository.loadMissingConversations();
	};
	void updateConversations();
	void conversationRepository.loadMissingConversations();

[atomrc]

Suggested change

	missingConversations.splice(0, missingConversations.length);
	this.conversationState.missingConversations = [];

more straightforward and easier to understand I believe

Actually this might be a bug, you don't want to reset the state when the request failed.
There might be some things to improve there.

You only want to remove the ones that were succesfully fetched on backend
