Description of problem:

The option to unset the hostgroup is not available

How reproducible:

100%

Is this issue a regression from an earlier version:

Not sure

Steps to Reproduce:

1. First, set the hostgroup

2. Then, Hosts - All Hosts, select the cotent host, click on the drop down menu, "Change Group"

3. In the next screen, the "Clear host group" is selected by default

Actual behavior:
In order to unset, we need to pick any other option on this dropdown menu, and after that, select once again "Clear host group"

Expected behavior:
The default option IMHO should be "Select host group". With that, this issue can be closed with no problem.
