Use alternative way for specifying multiple simplecov formatters
user
```ruby
require 'simplecov'
require 'codeclimate-test-reporter'
require 'coveralls'

Coveralls.wear!

SimpleCov.formatters = [
  SimpleCov::Formatter::HTMLFormatter,
  CodeClimate::TestReporter::Formatter,

SimpleCov.start do
  add_filter '/spec/'
end

require 'rspec'
