[18.0][OU-FIX] l10n_it: remove xmlid for taxes as they would be partially duplicated with possible critics errors during migration

[sergiocorato]

During migration from 17.0 of l10n_it the records with option auto_sequence="1" re-create theirs xmlids and sometimes they conflict with the existing records.

This PR remove completely them, to let Odoo re-create them safely.

This PR is for Italian module, maybe it could be a need of other localization modules too.

won't you delete manual customizations this way?

These reports are recreated from templates, so these manual customizations will be lost anyway.

These reports are only visible in EE but I don't use it so I don't know how they work, but how do you do customizations? They're only reports for what I can see.

[hbrunn]

yes right, people will have to live with that.

it's still weird to me that delete_records_safely_by_xml_id does not do the job here, did you investigate this? Note in any case that delete_childs does not do what you think it does: https://github.com/OCA/openupgradelib/blob/master/openupgradelib/openupgrade.py#L3638-L3642, is this possibly the problem? In my opinion, this is simply fixable by replacing "ir.ui.view" with record._name
