[FIX] account: Invoices & Refunds filters together

When both selected, these filters are expected
to display Invoices - OR - Refunds.

It was not the case, because the web client
expects to receive the domains normalized
when concatenating domains together with a
`|` statement.

Selecting both filters resulted in the below domain:

```
[
    '|',
    ('state','in',['open','paid']),
    ('type','in',('out_invoice','in_invoice'))`,
    ('state','in',['open','paid']),
    ('type','in',('out_refund','in_refund')),
]
```
Instead of
```
[
    '|',
    '&', ('state','in',['open','paid']), ('type','in',('out_invoice','in_invoice'))`,
    '&', ('state','in',['open','paid']), ('type','in',('out_refund','in_refund')),
]
```
