[FIX] sale: speed-up invoice creation

- At invoice creation, the stored fields that depends on `invoice_lines`
    are computed to be stored.
    This can slow down the invoice creation for a database with a lot of
    records on `account_move`.

    This commit speed-up the invoice creation by using SQL Joins to
    speed-up the searches.
    We cannot use `auto_join` on the `invoice_lines` field since it is
    not supported on many2many, thus we do it in SQL.
