If username/alias/UserPreference contains _ the notification won't work.

[ImCheesecake]

Describe the bug If a Telegram username/alias/UserPreference contains characters like '_', the notifications won't send. Instead you get an error.

To Reproduce Steps to reproduce the behavior:

1. Go to 'User Management'
2. Click on 'Details/Edit, then Notification Details'
3. Scroll down to 'Telegram'
4. Enter a username containing '_' (my user had the name L_bobo)
5. Make a request with as the user (or approve/deny as admin)
6. See error

Expected behavior I'm using {UserPreference} to tag users in Telegram and this user should be tagged like the other users who doesn't have a _ in their username

Additional context This user seems to trigger the mobile template each time he requests something new or if I approve/deny his request. Can't find the reason why either.
