tdf#80999 Canceling password prompt should abort detection

... instead of continuing the detection loop and being
"detected" as plain text. The detection API will from now
return a type based on the file extension only, which is
far more useful than "plain text" anyway. Plus the media
descriptor has a flag to indicate that the detection wasn't
completed, which can be also used by the loading code to
abort the loading process.
