Fix print job early termination during PDF conversion (M65)

Many webpages use window.print() immediately followed by window.close()
in JS. This means that the renderer and web contents are torn down
while the PDF is still being converted for the printer on Windows.
However, the web contents are not needed if the full PDF document has
already been rendered, so the PrintViewManager should just release the
query and allow conversion and spooling to complete instead of
cancelling the job.

The CL to send the Print Preview PDF directly to the PrintViewManager
broke this for users that use Print Preview because we no longer store an
extra copy of the web contents in the BackgroundPrintingManager. This has
been broken if using the system dialog since M64 or earlier.
