Damus: This commit
Settings: Local push notification setup
Steps:
1. Create a post from account 1
2. On account 2, make a reply to that post
3. Ensure we get a push notification with:
  - A title formatted as "<ACCOUNT_2_NAME> replied to your note"
  - A body with the contents of that reply
4. Click on that push notification. Ensure you are taken to the reply
5. Now make a post from account 2 and mention account 1 in it
6. Ensure push notification says that account 2 mentioned account 1 (i.e. does not talk about a reply)
