Keep the originating description when an unhandled error is a bare E_FAIL

A large share of unhandled errors reach OnUnhandledExceptionDetected as an
E_FAIL with no message and a stack that only shows Propagate() rethrowing it.
GetStowedException already tries to recover the real context, but it returns
null unless every step succeeds, so those reports carry nothing.

Read the description out of IRestrictedErrorInfo before giving up, and return
what was recovered even when the stowed frames are unavailable. The call was
already written out in a comment and left unused on the assumption that the
propagated managed exception would carry the details - which is exactly what
fails here.

WatchDog no longer overwrites the recovered string with the empty one from the
propagated exception.
