Bug: IMAP connector skips existing emails during initial sync

Description

The IMAP connector fails to synchronize existing/historical emails when setting up a new ingestion. Only new emails that arrive after the sync process starts are fetched. This results in data loss as all pre-existing emails in the mailbox are never imported.

Current Behavior

Set up a new IMAP ingestion for a mailbox containing existing emails
The connector fetches only new incoming emails
All emails that existed before the sync started are permanently skipped
This happens consistently on every fresh ingestion setup (at least with certain IMAP servers)

Expected Behavior

Initial sync should fetch ALL emails in the mailbox
Subsequent syncs should fetch only new emails (incremental sync)
No emails should be skipped or lost
