validate_setuo.py doesnt seem to check users with spaces in their name properly

[Medwynd]

On Windows, not sure on other systems, validate_setuo.py doesnt seem to check users with spaces in their name properly and says they have no games marked as owned.

For example:
bgg_username = "Randy Cox"

You get the error:
🔍 Checking BGG user 'Randy Cox'...
⚠️ BGG user 'Randy Cox' found but collection appears empty
Make sure you have games marked as 'owned' in your BGG collection

Also tried this with some other user names with spaces
🔍 Checking BGG user 'Tim Synge'...
⚠️ BGG user 'Tim Synge' found but collection appears empty
Make sure you have games marked as 'owned' in your BGG collection

🔍 Checking BGG user 'David Greene'...
⚠️ BGG user 'David Greene' found but collection appears empty
Make sure you have games marked as 'owned' in your BGG collection
