Use of '-c agro' removes the environment file from the Slurm stack

**Tool:**
Developer Platform

**Bug Description:**
When using:

./Start-All-DevEnv.bash -c agro

At some point between initialization and 'up', the aggressive clean is removing the environment file for the Slurms. Because of this, the DevEnv stops execution and the site doesn't come up.

I suspect this affects only Slurm because that stack is complicated and largely auto-generated and does things differently from the others. I'm not sure if it's better to change the behavior of the Slurms or to change the behavior of 'agro'. I think that if the latter cleaned the env directories before initialization, that would fix the problem

**To Reproduce:**
Start the DevEnv using the command above.

**Expected behavior**
Using a cleaning operation, even an aggressive one, does not remove critical files after they are generated.
