• Added request.Extra. Thank you @gmgalvan for your contribution!
• TestSuite now runs auto migrations if they're enabled before running the tests.
• TestSuite don't load config anymore if it's already loaded. This allows you to load a test configuration file using LoadFrom() before calling goyave.RunTest().
• response.JSON() doesn't remove hidden fields anymore. The use of json:"-" makes more sense and saves some execution time. Removing hidden fields manually is still possible.
