[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)'.
