does not work with rspec >= 3.0.0.beta

[pungoyal]

We have gem 'rspec-rails', '~> 3.0.0.beta' in the Gemfile.

On adding gem 'rspec-sidekiq', we get:

Bundler could not find compatible versions for gem "rspec-core":
  In Gemfile:
    rspec-sidekiq (>= 0) ruby depends on
      rspec-core (= 2.0.0) ruby

    rspec-rails (~> 3.0.0.beta) ruby depends on
      rspec-core (3.0.0.beta1)

Since rspec 3 is going to be in beta for sometime, it'd be good to fix it to work with pre released version(s).

Dup of #23. Master now has a loosen dependency on RSpec (>= 2.0.0) which should suit your needs. This is scheduled to be released in version 1.0.0 very soon.

Please reopen if you'd rather not do master and I'll consider a minor gem release
