fix: database crash issue

[1abhishekpandey]

Description

In this PR, we attempt to fix the DB crash issue occurring for a few % of users. This happens while the SDK is being initialised. We have removed the queue-related logic to prevent any hidden thread-related issues. Additionally, since we are now calling saveEvent() from the executor in the repository class, we no longer need a separate executor for the DBInsertionHandlerThread instance creation.
