Migrated error checking to remove the deprecated Faraday::Error namespace.
This change is not compatible with Typhoeus. The latest release is 1.3.1, but it’s still using the deprecated Faraday::Error namespace. This has been fixed on master, but the last release was November 6, 2018. Version 1.4.0 should be ok once it’s released.
Note: Faraday 1.0 drops official support for JRuby. It installs fine on the tests we run with JRuby in this repo, but it’s something we should pay attention to.
