      Description

      Removing a user from a group isn't reflected in getGroups even after a refresh. The following sequence fails in step 7.

      1) add test_user to a machine with group1
      2) add test_user to group2 on the machine
      3) yarn rmadmin -refreshUserToGroupsMappings (expected to refresh user to group mappings)
      4) yarn rmadmin -getGroups test_user (and ensure that user is in group2)
      5) remove user from group2 on the machine
      6) yarn rmadmin -refreshUserToGroupsMappings (expected to refresh user to group mappings)
      7) yarn rmadmin -getGroups test_user (and ensure that user NOT in group2)
