pegasus.runtime doesn't affect walltime

I was trying to change the walltime of jobs, configured for submission with slurm, and I noticed that setting the "pegasus.runtime" profile doesn't affect the walltime directive of the +remote_environment variable in the .sub file.
Instead Pegasus is setting a default value of 30000 seconds or 8h 20mins.

However, this happens when I specify the profile in the DAX. When I specify the profile in the TC it works as expected.

I've tested this with the latest panorama build and 4.8.3dev on workflow, and the issue is consistent in both cases.

I have attached a tar of the entire workflow directory. The generated files and submit folder can be found in the "myrun" directory.
To generate and plan a new workflow use "generate_plan.sh".
