When
donewas called twice inside of a test,undefinedwas being printed twice to stderr because internals.output expects an error object and the condition checking fordonebeing called twice was providing a string. Thus, the tester has no idea. Ask me how I know...I also added an extra carriage return at end of internals.output which keeps output clean when running tests in an automated tool such as nodemon.
Fixes #87
