QEMU changed the error message to:
"Tray of device 'drive-sata0-0-1' is not open"
and they may change the error massage in the future.
This updates the code to not depend on the text from the error message
but only on error itself. One more improvement is that we will store
the original error in case if it's not about tray is not open.
