Element opens a new window of dialogue, when you click on a notification.

**Describe the bug**
When I click on a new message notification, it opens a dialogue. But when I want to get back to main list of dialogues, I stay in opened dialogue. Maximum number of "windows" seems to be close to unlimited. I had up to ten of them; and you need to swipe back 10 times so.

**To Reproduce**
Steps to reproduce the behavior:
1. Open another app
2. Get notification about new message
3. Click on it
4. Dialogue is opened
5. Swipe back
6. You got to the same "window", not in Direct Messages.

**Expected behavior**
I expected to get in Direct Messages after swiping back, not in the same dialogue.
