InsufficientStorage error raised after running a full sync with KDP

[LianaHarris360]

Observed behavior

After running a full sync with KDP, the InsufficientStorage error was raised from the function _process_content_requests. The message Content download requests need 0B of free space was received which suggests that the user does not have enough storage, despite free_space being 15061171584

Possibly caused by this while statement or download_request assignment within content_request.py

Relevant:

• It was the first time this facility had synced to KDP
• Registration was skipped
• Lessons and quizzes were in the local facility data (the lessons & quizzes were created, and the resources used were then deleted from the device)

Expected behavior

If there is enough free space, the download_request should be able to be processed.

User-facing consequences

User devices unable to process download requests despite having enough space to do so.

I believe I fixed this in this PR #11083. There were several issues with the annotation queries
