Description of problem:
If you add an external host when IPA is install with integrated DNS and then
try to delete it while checking update dns, from the UI is appears like it is
successful, but does not delete the host.  The CLI returns an appropriate error
saying the DNS zone <zonename> was not found.

Summary     : The IPA authentication server
Description :
IPA is an integrated solution to provide centrally managed Identity (machine,
user, virtual machines, groups, authentication credentials), Policy
(configuration settings, access control information) and Audit (events,
logs, analysis thereof). If you are installing an IPA server you need
to install this package (in other words, most people should NOT install
this package).


How reproducible:
always

Steps to Reproduce:
1. install IPA server with integrated DNS
2. Log into the web UI as admin
3. Hosts --> Add
4. enter a host FQDN outside of the managed DNS domain and check the force
button (do not define an IP address)
5. delete the host and check Remove entries from DNS

Actual results:
Appears successful, but host is not deleted

Expected results:
Same as CLI - error is returned:
ipa: ERROR: DNS zone <zonename> not found
