Global task hooks - remove case references

[tobraha]

This pull creates a new elif for global_task hooks and normalizes the data referring to a specific case as it does not exist for a global task.

I'm using the following configuration for the webhook to post to Microsoft Teams:

{   
    "instance_url": "https://iris.dev",
    "webhooks": [
        {
            "name": "Microsoft Teams",
            "active": true,
            "trigger_on": [
                "on_postload_case_create",
                "on_postload_case_delete",
                "on_postload_ioc_create",
                "on_postload_ioc_update",
                "on_postload_evidence_create",
                "on_postload_evidence_update",
                "on_postload_task_create",
                "on_postload_task_update",
                "on_postload_global_task_create",
                "on_postload_global_task_update",
                "on_postload_report_create",
                "on_postload_activities_report_create"
                ],
            "request_url": "https://my.webhook.url/stuff",
            "request_rendering": "html", 
            "request_body": {
                "title" : "%TITLE%",
                "text" : "%DESCRIPTION%"
            }
        }
    ]
}

Bump module version to 1.0.3

Resolves #2

Moved this PR to Draft as I'm adding in another minor fix for the report webhooks as well. The report hook object doesn't define some of the case data, so the data looks something like this:

I'm adding in something like this, but I'm still testing things out.
