Fail only scheduled print jobs, i.e. handed to a service, if the service is disabled.

When a print service is disabled we assume all print jobs for it failed as we have
no way to know what happens to them. However we are also failing created print jobs,
i.e. ones not given to the service. Such jobs are in process of construction and
the print dialog is up. We should not fail such jobs as the dialog can still modify
their state and potentially select a print from a different service. Therefore, we
leave them alone and they will be failed if when constructed are passed to a
disabled/uninstalled service.
