fix: wbs-user:disable random password (#1015)

- Using just `random_bytes` does not guarantee a valid Bcrypt password
value
- Using the sha1 hashsum of that value should be sufficient

From time to time you would see this bug with the command failing in the
unit test:

```
1) Tests\Commands\DisableTest::testSuccess
ValueError: Bcrypt password must not contain null character
