It is possible to craft an input, that contains certain non-printing
unicode characters which would cause a failure of the normalization
process in some cases.

Curently the peppol edi mode is set to `demo` by default.

This happens because the system parameter determining the mode
(`account_edi_proxy_client.demo`) is initalised with `demo`.
This happens when installing module `account_edi_proxy_client` in a
post init hook:
https://github.com/odoo/odoo/blob/6f40f3a85d4c6edf43a427d8575c5c95c3005cd4/addons/account_edi_proxy_client/__init__.py#L6



After this commit we set the mode to `prod` when installing `account_peppol`
in the post init hook. Except if the DB is in demo mode or we have
proxy users already.

The modules `l10n_it_edi` and `account_peppol` are the only current modules depending
on `account_edi_proxy_client`.

In multi-company setups, incoming Peppol invoices were created in the current user's
company instead of the company of the receiving journal. The journal was not passed
to the EDI decoder, which fell back to `env.company`.

Passing `default_journal_id` in the context ensures the decoder uses the correct
journal and therefore the correct company.
