Neutron L3 Guest OS DNS Servers text fields are not returned to default settings (visually)

[Grigory Mikhailov]

Steps to Reproduce:

1. Create new environment with default settings.
2. Go to "Networks" tab and next to "Neutron L3" subtab.
3. Add some new "Guest OS DNS Servers" text fields (3 fields).
4. Remove "Guest OS DNS Servers" text fields with existing values ("8.8.4.4" and "8.8.8.8").
5. Click "Cancel Changes" button.

Expected result:
"Guest OS DNS Servers" text fields switched back to default values ("8.8.4.4" and "8.8.8.8").

Actual result:
"Guest OS DNS Servers" text fields are empty.
