[midPoint] Exit correlation rule instead of return empty

[Laza, Javier]

Hello folks

I have a OR correlation rule against an AD system that performs two verifications and works fine. I want to also add a new one that checks if the email of the account matches with any user email address

The problem I am facing is that some accounts doesn't have an email account, so I am getting a DISPUTED status, I think this is because it is returning an empty string or something like that and there are some users without an email as well, so Midpoint thinks several users matches the rule

I am checking if the account's email is empty and if so, then I return the email address (see the code below). Otherwise I don't want to return anything. I was thinking about setting a condition, but Midpoint complains when I try to use a <condition> tag inside the <q:equal> tag

<correlation>

                <q:or>
                    <q:equal>
                             --- Verification 1
                    </q:equal>

                    <q:equal>
                           --- Verification 2
                    </q:equal>


                    <q:equal>
                        <q:path xmlns:c="http://midpoint.evolveum.com/xml/ns/public/common/common-3">c:emailAddress</q:path>
