scheduler: Fix applying print-as-raster default

Currently, the default was applied only when present in the request, which is how lp behaves. However the application does not have to include defaults in the request, so we have to apply it in scheduler.

Additionally, this covers a case when print-as-raster is set by default, but we want to disable it in a specific request.
