In 20250101 & 20241201 Dump Need to handle labels without name

[ijabz]

In the discogs_20250101_labels.xml.gz and discogs_20241201_labels.xml.gz file label 212 DO NOT USE is missing a <name> element and this causes the exporter.py to fail I fixed the issue by modifying the xml file to add an empty <name> element but would better if code was fixed.

Can remove validate code with

 ```

def validate(self, label):
return True

instead of

def validate(self, label):
if not label.name:
return False

[ijabz]

That allows export but then in import need to remove that line from csv file

grep -G "^212,*,," -v csv-dir/label.csv > csv-dir/label.tmp; rm csv-dir/label.csv; mv csv-dir/label.tmp csv-dir/label.csv
