Do not mutate Sidekiq payload

[krasnoukhov]

Please take a look on this issue: mhfs/sidekiq-failures#88

Apparently your way of exception processing is quite destructive, since you're mutating context/msg variables here: https://github.com/rollbar/rollbar-gem/blob/master/lib/rollbar/sidekiq.rb

I don't think this is correct way to get rid from unwanted hash keys in terms of your exception handling. Please do not mutate, or duplicate the object before mutation.

Thank you!

Thanks for reporting! We'll look at this soon, most likely today.

Thanks @krasnoukhov! This was fixed in 82f6cb2 and released to rubygems as version 0.13.2. Let me know if things look OK when you get a chance to test it out
