CBL replication never finishes for replication filtering when doc count is 1000

Replication never finishes for test_replication_pull_filtering and test_replication_filter_access_revoke_document when filtering is done with 1000 docs. For 10 docs and 100 docs, test passes.

The issue is completed doesn't reaches to the exact count of expected total and after checking for sometime (150 iteration) we closes the replicator.

PS: This is with delta-sync disabled

As one can see because the replication never completes, we got key_error (additional field added in the doc) for the update on doc.
