ignore automation for non-automatables.

Since 4.7-1477-g2c6d595 Ardour implements Control::NotAutomatable.
This can lead to situations where automation exists for parameters that
were not supposed to be automatable, which in turn caused a
"programming-error" abort() in
RouteTimeAxisView::add_processor_automation_curve()
