OutputFormatter: Do not ignore DebugFormat

On Windows applications may print to the Windows internal
debug console. This output is retrieved and passed around as
DebugFormat as it is impossible to guess whether stdout or
stderr had been used when printing.
But output in DebugFormat had been ignored so far - fix this
and handle this as inside the Qt test parser.
