template: fix validation for required selects

Browse Source 
Since upgrading to Angular 1.6.1, selects with a default empty option
no longer show a popup with an error on submit. This fix adds an
empty option that is then removed with ng-if. Having the default
option set to null or undefined seems to be the cause of the bug.

The list of changes in 1.6 is here but could not find any obvious
cause for this bug:
