[IMP] sale_timesheet: Move not invoiced time sheet to new SOL

Description of the issue/feature this PR addresses:
There is no easy way to re-assign the time sheets to the correct SOL (changing
the task's SOL does not change the non-invoiced time sheets automatically)

Current behavior before PR:
On a project, if a user put a wrong sale order line, and after that he changes
this SOL, the timesheet line will not be moved.

Desired behavior after PR is merged:
On a project, if a user put a wrong sale order line, and after that he change
this SOL, all non invoiced timesheet line will be moved to new line.
