[ADD] sale_timesheet_invoice_description: New module

There's a constraint that limits the quantity over received one. Although it seems invalid
on services, we bypass it now with this.

- **Changes on tests :** now the timesheet needs to be linked to a
project task and this task is linked to the sale.order.line.

- **Changes on sale.py :** we cannot anymore find the timesheet related
to our future invoice line checking its create_date as v14 allows
to invoice only timesheets between two dates.
So I decided to refactor completely the way to match an invoice line
and its timesheet adding a `_link_timesheets_to_invoice_line` method
inspired by the native `_link_timesheets_to_invoice`

* adapted code to version 16.0 changes; for details see below
* added contributors
* updated i18n: sale_timesheet_invoice_description.pot, de.po
* run `pre-commit`

Linking timesheets to invoice lines: Respecting both the specified (in
context) start and end time, the same way as it is done for linking them
to the invoice itself.

Reworked preventing unbalanced invoice: Invoices must not and cannot be
unbalanced. This is now (in 16.0) done automatically. I.e., the
intermediate invoices, created while splitting lines, will no longer be
possibly unbalanced.
