Anh Thao Pham (pta) 637232a8c9 [FIX] base_vat: fixes format of Switzerland VAT 
- Install Contacts and Belgium - Accounting (l10n_be)
- Go to Contacts and create a new Contact:
  * Select Switzerland as Country
  * Enter "CHE-123.456.788 TVA" ad VAT
The VAT is auto-updated to "CHE123456788TVA", removing all special characters.

The entered VAT is converted to its minimal representation, stripping whitespaces and seperators.
And it is this compacted value that is stored.

As defined here (https://www.estv.admin.ch/estv/fr/home/mehrwertsteuer/fachinformationen/steuerpflicht/unternehmens-identifikationsnummer--uid-.html),
the Swiss VAT format should be CHE-XXX.XXX.XXX TVA.
Therefore, the VAT will be automatically formated to the official format.
