[FIX] mrp_account: no currency in analytics

Current behaviour:
Cannot add a Work Order to a Manufacturing Order
if the analytic account linked to the MO doesn't
have an associated company.

Expected behaviour:
Should be able to add a WO to a MO even
if the linked analytic account doesn't have
an associated company.

Steps to reproduce:
1. Activate analytic accounts
2. Activate work orders
3. Create an analytic account without company associated
4. Create a Manufacturing Order
5. In miscellaneous, link the analytic account
6. Try to add a WO line
7. Error log

Reason for the problem:
When trying to add a WO line, if the MO has been linked
to an analytic account, it checks for the currency in
the company in the analytic account, which was not
existent, since the company didn't exist.

Fix:
When trying to access currency, if the company in the analytic
account doesn't exist, it defaults to the company in the WO.
