title: Properties null when using /users but not when using /me/contacts
body: <p>When getting contacts from <code>https://graph.microsoft.com/v1.0/me/contacts</code> I get all properties for a user, ex:</p>
  
  <pre><code>{
    displayName: 'Joe Joeson',
    jobTitle: 'Administrator',
    department: 'HK',
    mobilePhone: '09823987234',
    businessPhones: '8934598743',
    mail: 'joe@mail.com',
  }
  </code></pre>
  
  <p>But when I get all users of the organization (with <code>https://graph.microsoft.com/v1.0/users?$select=displayName,jobTitle,department,mobilePhone,businessPhones,mail,userType</code>) the same contact doesnt get some properties, ex:</p>
  
  <pre><code>{
    displayName: 'Joe Joeson',
    jobTitle: null,
    department: null,
    mobilePhone: null,
    businessPhones: null,
    mail: 'joe@mail.com',
  }
  </code></pre>
  
  <p>Why? Its the same contact? Or am I missing something? Should I get all contacts from the organization in another way?</p>
  
  <p>I have confirmed that all properties are set in <code>https://portal.azure.com</code></p>
