Patch

Steps to reproduce:

1) Go to 'Firewall' -> 'New rule'.
2) Fill in the form for the new rule and check a radio button for "Source", "Destination" or "-Preset-" (under "Protocol") other than the first radio of the group.
3) Commit the form.
4) Edit the rule that has just been created.

Expected result:

The radio button checked in step 2 will be the only one in its group to have the "checked" attribute.

Actual result:

The radio button checked in step 2 will have the "checked" attribute *BUT* the first radio of the group will also have it.
