[FIX] account_3way_match: correct number of draft bills in dashboard

The number of bills to validate in the accounting dashboard is not the
same as the number of bills displayed when clicking on the button

Steps to reproduce:
1. Install Accounting and module `Vendor Bill: Release to Pay`
2. Go to Accounting > Vendors > Bills, create a new one with a due date
   set to yesterday and save it
3. Go to the accounting dashboard
4. In the 'Vendor Bills' journal, see that there is one bill to validate
5. Open the draft bills (by clicking on the `Bills to Validate` link),
   the number of bills in the view is greater than what was previously
   advertised

Solution:
Modify the context used in the action 'Bills to Validate'

Problem:
The module `account_3way_match` modified the query to get the number of
draft bills so the action should be adapted
