Move SyncNotes loop to the db #1871
Description
Currently the Store component implements the sync_notes by making multiple select_notes_since_block_by_tag_and_sender queries while the payload limit is not exceeded. We should move the loop to the DB to return multiple matching blocks instead of just the first matching one, avoiding the queries overhead. Additionally, the method currently takes a list of account_ids that is not being used so could be removed.
