Description of the problem:

MTA with invalid user no longer returns workflow status Error. In milestone 1 if we ran MTA with an invalid user the workflow would error out. Now it reports completed and is unable to send a failure notification because the user is invalid.

How reproducible:

100%

Steps to reproduce:

1. Run MTA with invalid user i.e. user:default/notauser

2. MTA returns Completed status and no notification or indication that the workflow failed

Actual results:

MTA returns Completed status and no notification or indication that the workflow failed

Expected results:

MTA returns Error status and some indication is provided to user about the failure. i.e. workflow failed because invalid user was provided
