[FIX] sale: config, timesheet if module account_analytic_analysis

In Settings > Sales, the onchange_timesheet ensure that if you check timesheet, it checks module_account_analytic_analysis.

Therefore, if module_account_analytic_analysis is installed, timesheet should be checked by default
Until now, it worked "luckily", because the onchange_timesheet of the field module_account_analytic_analysis was triggered before the onchange_timesheet of the timesheet field. Nevertheless, we shouldn't trust the onchange calls order.
[FIX] account_voucher: avoid trying unreconcile a move twice

When we cancel a voucher, we may be trying to unlink a reconciliation that was already removed on another move (just looking at the version in cache). In such cases, the unlink would fail with traceback. opw 610287
[FIX] project_long_term: avoid bad duplication of phases

When we duplicate a project, the related phases need to be duplicated as well but keeping references between each other.
e.g. 'project 1' with 'phase A' follwed by 'phase B' should become 'project 1 (copy)' with 'phase A (copy)' followed by 'phase B (copy)'.
