[Merge] lp:~zhangew401/usensord/fix-lp-1433590 into lp:usensord

Thanks a lot Seth.
@Mike, I think you need to decide if we only use one named unconfined profile or a better-than-unconfined profile.
Anyway I believe the name must be unique. Thanks so much. And also please send me the binary and tell me the name then I could test usensord. Thank you.
