The set-webkit-configuration is too aggressive at deleting config files when switch is not set.
This regressed in r275150 for Bug 176131.

Marking cq+ because enough builds have succeeded that I don't think I made the situation any worse, and I want to get this landed sooner rather than later. (I also compared this patch to set-webkit-configuration from r275150 and the subroutines I restored were unchanged as expected.)

All reviewed patches have been landed. Closing bug and clearing flags on attachment 424799 [details].
