[openstreetmap/openstreetmap-website] Specifiy invalid chars in username error message (#2044)

[Jamie Guthrie]

@tomhughes @gravitystorm  How should `display_name: nil` be handled?

The database has a NOT NULL constraint, but the validations explicitly state `allow_nil: true` and the original tests expected nil to pass

https://github.com/openstreetmap/openstreetmap-website/blob/b931d6f516d049ac42fcd70f33f130c252f5d0a9/test/unit/user_test.rb#L65-L69

    user.display_name = nil
    # Don't understand why it isn't allowing a nil value, 
    # when the validates statements specifically allow it
    # It appears the database does not allow null values
    assert !user.valid?

I've figured out why the validations were rejecting nil (the leading/trailing whitespaces validations were triggering on nil)

The new code now allows for a nil value to actually be valid now, providing thats the actual desired behaviour..

So, should nil be a valid value for display_name at the rails-level validations? (even though the database will reject it!) It doesn't really make sense to me to not validate against it
