fix: update filterHostGroupsQuery default argument

[0xliam]

Resolves #2164

Happy to work with the Icinga team on this PR - please let me know if anything needs changing.

When a role restricts users to a particular host group, e.g:

The following error is returned when trying to edit any host group:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'o.object_name' in 'where clause', query was: SELECT h.id FROM icinga_hostgroup AS h WHERE (id = '324') AND (o.object_name IN ('example'))

This PR updates the filterHostGroupsQuery default argument to 'h', as per the fix outlined suggested in #2164.

I've been using this in our production environment and it doesn't appear to have caused any adverse side effects.

Hi @0xliam, thanks for your submission! I fixed it in a slightly different place, where the method call context (directly after the related query) makes it more obvious, why that specific alias fits here.
