[FIX] l10n_it_edi: avoid conflict with peppol when switching to demo

Peppol and Italian edi both uses a proxy user. We should only use Italian
proxy users when checking demo mode otherwise Peppol production proxy users
can interfere and trigger an error like 'Company already have prod connection'.
Also we don't want to delete demo Peppol connections.
