New Route dialog: add fallback default selection

This fixes an issue with Mixbus. If the default "Create Audio Tracks.."
template/script is not available. Nothing is selected.

Selecting a type/template is required to update various other dialog
fields. eg. "Name" field.

Previously: Create VCA. OK+Close. Re-open dialog. Now the
implicit default was "Audio Track" but the Name-field still showed "VCA".
