[FIX] account: added a regex verification when adding a partner mapping

Steps to reproduce the bug :

- Go to accounting > Configuration > Reconciliation Models
- Create a new reconciliation model
- Select the “Match existing invoices/bills” type
- In the field “Match Invoice/bill with” choose “Label”
- Add a new partner mapping > encode in "Find text in label" an erroneous regex like “*test” > choose any partner
- Go to accounting Dashboard > click on “Bank”
- Create a new Bank statement> add new transaction without selecting “Partner”
- Post the created bank statements > Reconcile it

Problem :
An error is triggered because the regex is wrong.
