Fix node_modules resolution error messages

Summary:
We could probably relieve a lot of pain (in [this issue](https://github.com/facebook/react-native/issues/4968) specifically) by fixing the error message for when a module cannot be resolved after trying every relevant `node_modules` directory.

Currently, you get a confusing error message that only gives you the last `node_modules` directory checked. By creating the error message where we can access the `searchQueue`, we're able to provide all of the attempted `node_modules` directories.

Here's an example error message:

```
Unable to resolve module leftpad from /Users/aleclarson/ReactProject/src/stuff/index.js:
Module does not exist in the module map or as these directories:
  /Users/aleclarson/ReactProject/src/stuff/node_modules/leftpad
  /Users/aleclarson/ReactProject/src/node_modules/leftpad
  /Users/aleclarson/ReactProject/node_modules/leftpad
  /Users/aleclarson/node_modules/leftpad
  /Users/node_modules/leftpad
```
