Allow single user sync of new users

[tomneedham]

Steps to reproduce

1. Add a new user to LDAP
2. Run single user sync from the CLI using the username attribute

Expected behaviour

The new user is discovered, account created and synced.

Actual behaviour

The account is not found.

HEAD@ ef8e4a4
user_ldap 0.10.0

This is because core checks the backend for userExists($uid) with the value passed in from the command line argument. LDAP->userExists() is here.

This will check for cached users within this process, then look for mapped users, but no more than this. So any not yet discovered user will not be found. This method should be extended to also do a search with $backed->getUsers($uid, 1, 0). Core must then translate the uid from the input to the one returned through this method before creating an account and syncing.
