host_not found error on toggling manage/unmanged host

Description of problem:
I discovered a host and when I tried to provision that manually I clicked on 'provision'. On Edit host form, found two buttons:
- unmanaged host and
- disassociate host

On clicking any of them, page is redirected and throws error:

'Host Not found'

Version-Release number of selected component (if applicable):
sat6.1 GA snap5

How reproducible:
always

Steps to Reproduce:
1. discover a host
2. provision it
3.

Actual results:
on edit host page, on clicking unmanaged host or disassociate host throws 'Host not found error on UI.

Expected results:
First I'm not sure what's the purpose of these buttons. I *think* this is to make managed or unmanaged host or to disassociate a host from a VM image.

But if these are not relevant anyway with discovery then we should disable them while provisioning a discovered host.
