Proposed changes

Since we upgraded to react-navigation 7 and it had several breaking changes, tablets weren't working properly and sometimes RoomView could be instantiated more than once on mobile, which is wrong.
I've reviewed all navigation changes to RoomView and leaving RoomView and made the necessary changes to cover both mobile and tablet.

Here are the events I reviewed:

• Mark message as unread
• Mark thread as unread
• User deletes a room/team
• User is removed from a room/team (while the room is open)
• Leave room/team
• Go to message from in-app notification
• Go to thread from ThreadMessagesView
• Go to message from search
• Go to message from Mentions/Starred/Pinned
• Go to discussion from DiscussionsView/message
• Go to room from RoomInfo (Message)
• Omni
• Go to thread from message
• Push notification deep link
• Create channel
• Directory

It also removes the window logic from subscriptions/room mentioned in #6057.
It's a potential fix for it.
It may need a separate PR, but it's ok to merge it here until we decide otherwise.

How to test or reproduce

// post-message.js
function postMessage() {
  const url = 'https://' + host + '/api/v1/chat.postMessage';
  const response = http.post(url, {
    headers: { 
      'Content-Type': 'application/json', 
      'x-auth-token': token, 
      'x-user-id': userId
    },
    body: JSON.stringify(
      {
        roomId: rid,
        text: msg
      }
    )
  });

  console.log('response', response.body);

  output.messageId = JSON.parse(response.body).message._id;

  return response.ok;
}

postMessage();

# message-in-background.yml
appId: chat.rocket.reactnative
env:
  host: HOST
  rid: RID
  token: TOKEN
  userId: USER_ID

- evalScript: ${output.counter = 0}
- repeat:

    commands:
