As a developer I want to add multiple templates for a Landing Page Block, as easy as described in the documentation (https://doc.ez.no/pages/viewpage.action?pageId=31430614).

1. Create a Block for Landing Page
2. Add another template to default_layouts.yml config

Expected behavior:
A select dropddown appears in the landing page block settings overlay for the defined templates...as it does for the schedule block

Behavior:
Nothing happens
