Update munger.js

[xjamundx]

Currently if there's a template error in kraken we sometimes get this error:

Cannot find module './'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Function.m._load (/Users/jamuferguson/dev/paypal/p2pnodeweb/node_modules/

With this change we now get the following instead:

Could not load components/component-header-footer/header/vx-header: Cannot find module './'
    at /Users/jamuferguson/dev/paypal/p2pnodeweb/node_modules/engine-munger/lib/munger.js:77:11
    at BufferList.<anonymous> (/Users/jamuferguson/dev/paypal/p2pnodeweb/node_modules/engine-munger/view/dust.js:53:24)
    at BufferList.<anonymous> (/Users/jamuferguson/dev/paypal/p2pnodeweb/node_modules/bl/bl.js:16:14)

It's arguably way more helpful.

Much better!

Couple unit tests failing. I can help look into it tomorrow if necessary.

Thanks @grawk the actual root issue here that caused me to even add this was dust trying to find some missing content. Trying to figure out if there's an even better way to display that error message.

I'll try to fix the tests locally and rebase though.

I found a further root cause. Will close and continue. It's looking like this line here should probably throw instead of callback:
https://github.com/krakenjs/localizr/blob/v1.x/lib/bundle.js#L70

And then furthermore I think this in that section looks like this:

{
  file: '/Users/jamuferguson/dev/paypal/p2pnodeweb/locales',
  type: '',
  name: 'locales'
}

Which should alert us to the fact that we're not really able to read the properties file. Trying to figure out if we can fail even earlier than that.

And here's where we pass that faulty "property file path":
https://github.com/krakenjs/engine-munger/blob/v0.2.x/view/dust.js#L43

We should not be defaulting to i18n.contentPath here as this is expecting the path to a specific property file and will fairly silently fail.....Working to find the best alternative!

There's a slightly better solution here:
