Do not await bookmark scheduling on application start to prevent startup from hanging

[jwdb]

I will have to say this is my suggestion on fixing the problem directly, there might be a better way of solving this problem. For example by moving the entire scheduling into a background worker instead of running directly in the tenant activated event.

Purpose

This makes the Application not wait for all the bookmarks to be queued before continueing the start of the application.

Description

Problem

this solves the problem described in #7470

Solution

By not awaiting the scheduling of the bookmarks, the program flow will continue and not hang the IHostedService responsible of activating the tenants

---

Verification

This can be verified by queuing a large amount of bookmarks and restarting the application. After this change the startup will continue while the log wil show the bookmarks are still being enqueued
