`\OC\User\Database::createUser` can throw a PHP exception in case the UID is longer than
permitted in the database. This is against it's PHPDocs and we should cast this to `false`,
so that the regular error handling triggers in.
The easiest way to reproduce is on MySQL:
1. Create user `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa` in admin panel
2. Create user `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa` in admin panel again
3. See SQL exception as error message

The constructor is iniitiated already very early in base.php, thus requiring this here will break the setup and some more. For now we probably have to live with a static function call here thus.

For guest users on every request executes query:
SELECT `uid`, `displayname` FROM `users` WHERE LOWER(`uid`) = LOWER(null)
as I see, uid can't be equal to null by design.
We always query the database backend. Even if we use a different one
(ldap for example). Now we do this everytime we try to get a user object
so caching that a user is not in the DB safes some queries on each
request then (at least 2 what I found).
