[keycloak-user] Keycloak user credentials clean up

[Francisco Montada]

Hi Team
We are facing the problem with the user credentials clean up, the uses
cases are two and are consisten

1. From the Keycloak Web Console, sometime if I remove more that one role
at the same time, is happen the credential clean up.
2. After redeploy the server, the credential for some users are being clean
up


This is how the user credentials looks after the clean up
 "credentials" : [
        {
            "value" : "ZTA3VTu2d7X6Cl/iSWKjGBGb5bJUFBto1EiOs8AjLj5rI
KkMo2Wzymgm8rdPP27LMBBovNw8nxpDvcp4tniCqw=="
        }
    ],

The problem is that after that Keycloak can no do anything with that user
because the server start getting NullpointerException

03:36:36,031 ERROR [io.undertow.request] (default task-5) UT005023:
