Missing data in outgoing webhooks with `userCreated` event trigger (as well as roomCreated/Archived/Join/Left triggers)

Description:

After updating to 7.7.1 the outgoing webhook requests for "User created" event triggers don't contain the required data anymore.

Steps to reproduce:

1. Go to admin panel > Integrations
2. Create a new outgoing webhook with event trigger "User created" (value of other fields are not important)
3. Create a new user to trigger the webhook
4. Check the "Data Passed to URL" value in the webhook history, which is missing the important data like user_id

Expected behavior:

The "Data Passed to URL" should contain all required data such as user_id and user_name like in this example before the update:

Actual behavior:

The "Data Passed to URL" only contains token and bot:

Server Setup Information:

• Version of Rocket.Chat Server: 7.7.1 and 7.8.0-develop
• Operating System: Linux

Additional context

After investigating this, I believe the issue was was caused by this commit (triggerHandler.ts, Line 264). The check if room or message is defined prevents the proper data added for triggers that don't require a room or message. I will create a PR to fix this.

Start in triggerHandler.ts around line 264 and reproduce the userCreated webhook, then compare its payload with the expected user_id and user_name fields. Check the roomCreated, Archived, Join, and Left triggers as well; done means their outgoing webhook data is no longer reduced to only token and bot when room or message is absent.
