Print to PDF putting a pring job in a wrong state.

When printing to a PDF file we get a Uri from the storage APIs
and write the content. Once the file is written to storage the
print job is completed and there is print service involved. Th
spooler was wrongly putting the job in a failed state instead
of a complete state.
