[FIX] l10n_hu_edi: Cleanup post-init code

This commit comes as an apology for the horrible code I wrote in
PR odoo#166043 in order for the installation of `l10n_hu_edi` to not fail
if some of the default Hungarian taxes (defined in `l10n_hu`) had been
deleted.

Instead of rolling back the loading of the EDI-specific fields if some
taxes don't exist, we can just load those fields on the taxes that do
exist. Which is a lot cleaner and simpler. Sorry again!
