Ensure index attributes call removed while creating a document

Changes proposed ✍️

• Ensuring index properties on each creates is unnecessary, removed the ensureIndexSettings call on create a document.
• I'll provide util functions to change these settings in a migration manner, tho this needs to be merged so the task queue can process the already existing tasks in the queue
