Before this commit, the `recover` parameter is used when parsing the xml files. The issue with this, is that it will allow and parse broken XML files, and the error messages in JS will not be related to the issue on the broken XML. Now, the parser is stricter, and the broken template will be replaced with an error template with a compressive error message of the parsing error. closes odoo/odoo#139818 Task-id: 3420400 Signed-off-by: Xavier Dollé (xdo) <xdo@odoo.com>
