[FIX] account: analytic lines access with timesheet manager

When validating a invoice, the billing user should have access (read) for all analytic
lines. A problem appears when timesheet is installed, since there is a mismatch with
ir.rule (a timesheet is an analytic line with a project set).
The rule "account.analytic.line.billing.user" already exists for this problem, but should
be extended to work in any case.

To reproduce:
- set a user as timesheet manager and billing user
- try to validate an invoice (or post an expense)
- got an access error with "account.analytic.line.timesheet.manager"
