LDAP users, contact data is deleted.

User Manager: 15.0.21
Type Directory: OpenLDAP Directory

This problem only happens with users imported from LDAP, with the local FreePBX users the failure does not occur.

When importing users from LDAP, the data is updated correctly in "contactmanager_group_entries" (displayname, fname, iname, etc ...).

But if we edit some of the users and even if you do not modify anything, by clicking on the "submit" button the records in the "contactmanager_group_entries" table are updated, and the columns "displayname", "fname", "lname", " title "," company "and" addresss "appear empty.

To solve it, it is necessary to force the update of the data from the LDAP server.
