[FIX] ir_values: fallback when no condition

When searching for default values, if we set a condition (e.g. 'type=out_invoice'), fetch also the default values without any condition set. Thanks to the order by clause, the one with a condition have an higher priority than the one without and will not affect existing result.
This fixes default journal/currency on an invoice where the journal is retrieved in the onchange_company_id method (domain is forced). Without this patch only ir.values with a domain set will match, opw 610645
[FIX] hr_timesheet: missing '&' in domain clause

To search the contracts for payroll, the domain is constructed with three clauses. Each of these clauses needs to start with a '&' to make sure they are correctly combined with the OR clause'

[FIX] account: better error message when regenarating opening entries (opw 606923)

With this, we make sure people will first cancel the entries before regeneraing the entries.
[FIX] sale: only propose services for pay advances

When creating an invoice from a sale order, if the user choose to invoice a fixed price (deposit), he has the possibility to choose an advance product. As described in the help message, this product should be a service product. Therefore, we add a domain so only services are displayed in the dropdown list

[FIX] mail: display translated model name at record creation

When a record is created, if it inherits from mail.thread, a message 'OBJECT created' is posted. 'created' is translated but the name of the model wasn't.

[FIX] stock: do not set user_id on prepare_invoice_group

The user_id is already set by the prepare_invoice method, which is called before the prepare_invoice_group (the user_id is already set, thus)
Besides, _prepare_invoice is overriden in sale_stock, to set the picking sale order salesman as user_id, and, without this correct, grouping invoicse by partner re-set the user_id to uid, which is wrong.

To reduce the remaining leaves of an employee, the user should cancel and remove the allocation request
