Bot Accounts get created with email notification of Immediately

[mattermod]

When a bot account is created the email notifications are set to immediately. Depending on server config, this makes sense for other accounts but, bot accounts should have this set to never. Because bots have token email addresses, every time someone DMs a bot, it will cause a bounce-back on the corresponding mail server.

This was reported by a community member here #15769

Steps:

• Set Enable Email Notifications: to true
• Set Enable Email Batching: to false
• Enable bot creation
• Create a bot
• Check NotifyProps in the Users table for the bot you just created

Observed: email":"true and there is no way to change it via the UI as the bot cannot login. The mail server will now attempt to deliver notifications for DMs
Expected: When a Bot is created or a user is converted to a bot, set email notifications to never or some other solution that prevents Mattermost from trying to send out email notifications when the user is a bot.
