Pedro M. Baeza 3221745c32 [FIX] account_asset_management: Display significant information about the error
As it was, the information put was like:

```
Error mientras se procesa el activo '....': <class 'odoo.exceptions.UserError'>
```

Now, it is:

```
Error mientras se procesa el activo '....': UserError("No puedes usar esta cuenta (...) en este diario, consulta la sección 'Control-Acceso' en la pestaña 'Configuración avanzada' en el diario relacionado.")
```
