in Deck comments, replies to comments with mentions results in receiving an email notification from oneself as if it was a new one

### Steps to reproduce 1. Activate email reminders every 3h 2. Activate email notifications for **A comment was created on a card** (it may also have happened without the tick, I`m not sure) 3. Create a Deck card as UserA 4. Share board and cardX with UserB 5. Make a comment as UserA on the card mentioning @UserB (5th of July) 6. The day after, UserB replies to UserA's comment containing the mention @UserB (6th of July) 7. @UserB receives an email telling him the following: `Today at 12:30 PM. UserB has mentioned you in a comment on cardX.` (6th of July) ### Expected behaviour UserB should not get a notification for replying to a card where his mention is present. Moreover, being a reply, the beginning of the message is the whole comment of UserA to UserB, which is confusing because one would expect to be presented with the reply itself and not the message of UserA _only_. The email UserB received may very well be a reminder, since it contains many reminders. ### Actual behavior UserB gets a notification for replying to a card where his mention is present. It may very well be that the reason for this is not the reply to a message with the mention, but what is described in issue nextcloud/deck#4304 ### Server configuration
