"icinga2 object list -t Host" misses host groups

[oxzi]

Describe the bug

Starting with an Icinga 2 setup with hosts and these hosts being part of host groups. When querying these hosts via icinga2 object list -t Host, no groups are being listed.

$ icinga2 object list -t Host | grep groups
  * groups = [ ]
  * groups = [ ]
  * groups = [ ]
[ . . . ]

However, this information is available when using the Icinga 2 API.

curl -k -s -S -u "icingadb-web:$ICINGA2_API_PASSWORD" -H 'Accept: application/json' 'https://localhost:5665/v1/objects/hosts?pretty=1' | grep -A 1 'groups": \[$'
                "groups": [
                    "openbsd-servers"
--
                "groups": [
                    "openbsd-servers"
--
                "groups": [
                    "linux-servers"

To Reproduce

Create one or multiple Host objects, place these in HostGroups, execute the commands from above.

This works fine for me:

~/Workspace/icinga2 (master ✗) icinga2 object list -t Host --name icinga2
Object 'icinga2' of type 'Host':
  % declared in '/Users/yhabteab/Workspace/icinga2/prefix/etc/icinga2/conf.d/hosts.conf', lines 22:1-22:21
  * __name = "icinga2"
...
  * groups = [ "groot" ]
    % = modified in '/Users/yhabteab/Workspace/icinga2/prefix/etc/icinga2/conf.d/hosts.conf', lines 30:3-30:22

API created host:

~/Workspace/icinga2 (master ✗) icinga2 daemon -C --dump-objects
~/Workspace/icinga2 (master ✗) icinga2 object list -t Host --name icinga2
Object 'icinga2' of type 'Host':
  % declared in '/Users/yhabteab/Workspace/icinga2/prefix/var/lib/icinga2/api/packages/_api/96a0468e-9e30-46f3-b5f1-8696393d1d01/conf.d/hosts/icinga2.conf', lines 1:0-1:20
  * __name = "icinga2"

Ah, host groups with assign where host.name ... don't show up!
