PyJobTransforms.trfAMI: fix handling of pyAMI.exception.Error exceptions
While handling pyAMI.exception.Error
exceptions, the trfAMI.py module was attempting to access the message
attribute of these exceptions in order to check the associated error message, but this results in AttributeError: 'Error' object has no attribute 'message'
. In such cases str(e)
should be used to access the message string.
