REST API content/page/template/isRenderable always returns true for a page template, even when it doesn't have a controller. Fix so that it returns false when controller is not selected.
When this is done, roll back this commit and test that:
when creating a new page template the editor panel is not blank but shows descriptor selector
Preview button is disabled for a page template with no controller both in the Grid and the Wizard
Preview panel in the grid shows "Preview not available" text for a page template with no controller
