Duplicate volumes detail request on find_resource

[Gorka Eguileor]

utils.find_resource has a duplicate find request by display_name and this affects any command that searches for a volume by display_name or any command that searches for non existent volumes.

You can see this by running
   cinder --debug show fake_disk_name

You will see that you get 4 request to volumes/detail?all_tenants=1
And there should only be 3, by:
- human_id
- name
- display_name

But display_name is tried twice.
