babel-plugin-redux-saga crashes sagas - Object.defineProperty called on non-object

[ChrisWiles]

Steps to reproduce

yield something that isn't an object.

Description of the bug/issue

The plugin should check that that it transforming an object before calling defineProperty.

TypeError: Object.defineProperty called on non-object

Example

// I know there is nothing to yield here, but this would normaly be fine without the plugin 
function* foo() {
  yield 20; //  crash: Object.defineProperty called on non-object
}

Thanks for the report - it's definitely something that we should fix. Not sure though when this will happen, unless you would like to help to implement a fix for this.
