[FIX] l10n_ke_edi_tremol: error message spacing

Since batching was introduced for posting invoices with the fiscal
device (in https://github.com/odoo/odoo/pull/107852), the error messages
that are generated when doing the pre-post validation had to be grouped
by the invoice name. However, there is no line break between the groups
of messages, and thus the "Invalid invoice configuration on (invoice
name)" can appear on the end of the previous line, which is quite
confusing.

This commit inserts a new line at the end of each error message string,
so that the error messages displayed to the user are grouped
appropriately by the invoice to which they refer.

closes odoo/odoo#111502
