Do not try to access length of minified code if minification failed

[kmoe]

If UglifyJS.minify(src, options) (line 116) fails, the result object will have the following form:

{
  error: [uglifyjs stack trace]
}

In this case, attempting to access result.code.length causes broccoli to fail with Cannot read property 'length' of undefined, and the error report file shows only the stack trace for this error, not the actual minification error.

Moving the debug line below the throw ensures that the user sees the real cause of the error (the uglifyjs stack trace) in the console and error report file.

Happy to add example or test if necessary - discovered during a long broccoli debugging session...
