fix reserved_ip not tested

[resmo]

Description

When the ip_reserved module was created, the instance module was not ready yet. That is why test were disabled and forgotten to enable them, when instance module became available.

Due to the lack of testing a change in the method query_list was missed to adjust in the ip_reserved module which broke the module.
