Fixed commander API bug with this.opts()

[jordaaash]

[...]/node_modules/react-native-webpack-server/bin/rnws.js:126
    const opts = options.opts();
                         ^

TypeError: options.opts is not a function

The correct Commander method for getting the options passed is this.opts(). This means that rwns bundle has not been functioning correctly when called with options since 14eecdf

Thanks for the PR!

Weird, that's not what I've been seeing. All options seem to work just fine here. In fact, reading the commander code at https://github.com/tj/commander.js/blob/272e22ffa8f7dea42ebc831bd4ad900ae893a17a/index.js#L292-L301, it seems that this.opts() and options.opts() should be equivalent, because the action callback will always be called with self as this and as the last (and in our case only) argument.

Can you provide detailed steps to reproduce (environment, exact version numbers, etc.) on how you got the above error?

You know what, this was due to running the bin via node (using the debugger while testing), which screwed up the options passed to the bundle command. Closing this.
