_log_console_output do not raise NotFound

_log_console_output is typically used for debugging purposes,
usually in an exception handler. It can receive a list of
servers for printing the serial console's output,
but it is possible, in the mean time the server get deleted.
Raising NotFound in the above case, makes very confusing to
 read the debug log.
