Safely manage not awaited calls

[WorldWideWest]

Description

Multiple calls on methods implemented in email service weren't handled properly. Make sure to handle them, follow this article for more info on that How to safely call an async method in C# without await and use the logger to log the exception

These are the places where I found unhandled calls:

1. src/Template.Application/Identity/Commands/ResendConfirmationEmail/ResendConfirmationEmailCommandHandler.cs
2. src/Template.Application/Identity/Commands/ForgotPassword/ForgotPasswordCommandHandler.cs
3. src/Template.Application/Identity/Commands/CreateUser/CreateUserCommandHandler.cs

Acceptance Criteria

• All three places are adjusted and log the exception into the terminal
