[Swift-devel] r2509 breaks GRAM2 job submission by adding an unknown attribute

[Ben Clifford]

r2509 adds a tr attribute to all jobs, which causes gram2 job submissions 
to fail like this:

stdout.txt: 

----

Caused by:
        Cannot submit job
Caused by:
        Parameter not supported

(on tg-uc and tp)

r2515 reverts r2509.
