Downloads issued invoices

The invoices downloaded from the xunnel-app also needs to be issued (emitidas).

Modules to modify:

In xunnel-invoice
  1. The wizard xunnel.attachments.wizard must have a invoice_type selection field (with related=False, default='recibidas') storing the values [('emitidas', 'Issued invoices'), ('recibidas', 'Invoices received')].
  2. That value must be passed to the method _sync_xunnel_attachments and update the dictionary sent in self._xunnel('get_invoices_sat', values)
In xunnel-app
  1. The method _get_invoices_sat is going to receive the key/value you updated in xunnel-invoice step 2.
  2. Change the way the keywords are sent in this line, must be either 'recibidas,vigente' or 'emitidas,vigente'. To make this, use the parameter you just sent.
