Null Password - Setting a new password doesn't check for empty spaces

How it was found

Hi Again!

As seen your website at https://demo.weblate.org/accounts/password/

Your password can't be too similar to your other personal information. Your password must contain at least 6 characters. Your password can't be a commonly used password. Your password can't be entirely numeric.

I found that it is possible to create a password with empty spaces, not useful anyway but renders the password security weak.

Reproduction Steps

• Create a new account
• Load the link sent to your mail
• Now, set password to six spaces (tapping the space bar 6 times)
• You'll get a success message
