[FIX] account: performance of search panel

This fixes the performance of the search panel of `account.move.line`
Menu > Accounting > Accounting > Journal Items
The control panel based on the accounts' roots was the issue (call to
`search_panel_select_range`)

Before this fix, the entire table was read through the use of a
`read_group`.
Since the data returned by the `read_group` is not interresting in our
case, we can simply do a lateral join on an indexed column with a limit
in order to improve the performances.
