Relax rule: Spacing around * in generator functions

There is an issue with the interaction between babel-eslint and eslint.
See eslint/eslint#6274

I think we'll just have to disable the generator-star-spacing rule
until ESLint has support for the async keyword. Bummer.

See standard/standard#564 (comment)
