[FIX] l10n_es_edi_sii: remove call to _post_invoice_edi

a66ac063e01afbcc5bec2e6f56da81340b28aaa7 introduced the use of
`_post_invoice_edi` method on `account.edi.format`, as it is a forward
port of a fix in v15, where this method still existed.
But it doesn't exist anymore in v16, due to
0e5626ca5126e6fea7fb95b694229948540764d7.

The fix is to use the method specific to the spain edi:
`_l10n_es_edi_sii_post_invoices`
