When querying about hosts via API and using this=true the API returns wrong subtotal count. This happens when the query matches more records than what is the current per_page setting.

Example:

Search for "*" on 30 hosts in total with per page being 5 will result in:

results: [5 hosts...]
per_page: 5
total: 30
subtotal: 5

In this example the expected result is subtotal being 30.

Additional info:
The issue is caused by calling `pluck` on the original active record relation when thin=true is used.
