Forgetting to add a name to an alert profile causes template selection to be cleared in form

[Morten Brekkevold]

Steps to reproduce (NAV 4.3.2):

1. Go to Alert Profiles, click to create a new profile.
2. Select a time period template from the dropdown
3. Click submit.

The resulting page view complains that the profile name field is required. The dropdown selection has been /cleared/. The user will likely miss this, as they press the submit button again.
