Group description not retrieved through REST

Below HF09

1. install an LDAP server with at least 1 group with a description
2. install Nuxeo 8.10 HF08
3. configure Nuxeo to connect to the LDAP
4. connect as Administrator
5. search users with * as filter
6. head over to the groups tab
7. search groups with * as filter
8. check the groups and observe the description appears in the result list
9. go into one group entry, the description is missing
10. access it through REST using a command similar to:

    curl -u Administrator:Administrator http://localhost:8080/nuxeo/api/v1/group/firstgroup | json_pp

    {
       "groupname" : "firstgroup",
       "grouplabel" : "my description label",
       "entity-type" : "group"
    }
    

    In the LDAP logs, the attributes returned are:

    memberURL senateLabel tenantid objectClass member description cn
    

With HF09

1. install an LDAP server with at least 1 group with a description
2. install Nuxeo 8.10 HF09
3. configure Nuxeo to connect to the LDAP
4. connect as Administrator
5. check the groups and observe the description appears
6. access it through REST using a command similar to:

   curl -u Administrator:Administrator http://localhost:8080/nuxeo/api/v1/group/firstgroup | json_pp

   {
      "groupname" : "firstgroup",
      "grouplabel" : "firstgroup",
      "entity-type" : "group"
   }
   

   The label (description) is not retrieved.

7. In the LDAP logs, the attributes returned are:

   cn memberURL
   

This may be due to the following fix in HF09 (NXP-20066) but this does not explain why the description is displayed in the JSF UI.

Also the fix version may be extended if it is confirmed to be a regression to 6.0 and 7.10.
