undefined method `split' for nil:NilClass occur in assets:precompile

[AknEp]

In my heroku enviroment, undefined methodsplit' for nil:NilClasswas occurred inassets:precompile`.

I found Rake::VERSION and RAKEVERSION is nil. so rollbar gem crashes in Rollbar::Rake.patch!

I don't know why Rake Version const was not defined ...
my Gemfile.lock has below.., and bundle install command success.

rake (11.1.1)

but, I think rollbar should be more robust.

oops! Thank you for your quick response. sorry for my no-checking other issues.

but I think similar problem should occur, so #397 it not enough. I'll send PR.
