[FIX] account_voucher: do not unlink records in onchange method

The method recompute_voucher_lines() is used by several onchange methods of
account.voucher.  It used to unlink() the voucher lines before recomputing new
voucher lines.  As a side effect, if you edit a voucher and discard your
changes, your voucher has lost its lines, although you did not save your
changes!  Moreover, the call to unlink() is invalidating the record cache,
which screws up completely the onchange() method.

So, instead of unlinking the existing lines, the onchange generates commands
[(2, id), ...] to remove the existing lines only when saving the changes.

[FIX] fix context problem in graph view

The group_by query expects the context to have group_by_no_leaf = true,
so we can not just blindly forward the context to the groupby query.
This is a defensive way to fix the problem, to avoid other possible
crashes.  But the context shouldn't have group_by_no_leaf anyway,
it does not make sense to explicitely do that in the action

[FIX] website_sale: auto-confirm free orders upon cart validation

Orders are normally confirmed when the payment transaction
is processed, but there is no transaction for free orders.
This caused them to stay in draft until manually cancelled.
