`omero script replace` "loses" official script if invalid

The workflow:

omero script upload --official my-script.py
# Begin loop
omero script replace /my-script.py my-script.py
# End loop

is a fast method of developing a script in OMERO. However, if the script is invalid, a subsequent call to replace will fail since the original script is no longer in place. The Script service should likely catch the exception and attempt to roll back the change:

$ omero script replace /my-script.py my-script.py
