Excon gem is specified as a runtime dependency, but only used in tests

[kindjar]

It seems like faraday is the http library actually used by the gem itself... I found it odd that the gem declared two different http libraries as runtime dependencie. It looks like the excon gem was added for use with some tests, but since it's listed as a runtime dependency in the gemspec, it gets installed by bundler in my app that doesn't use excon. Is there some reason the dependency is set up this way?
