API example error related to ownProps

[carloluis]

The API doc. section: The arity of mapStateToProps and mapDispatchToProps determines whether they receive ownProps has some code examples, but the console.log hint on the ownProps in second code excerpt is wrong. It says undefined instead of the empty object used as default value for the parameter.

I'll create a PR with this minor update/fix:

const mapStateToProps = (state, ownProps = {}) => {
  console.log(state); // state
-  console.log(ownProps); // undefined
+  console.log(ownProps); // {}
}
