Confusing error message when a non-existent file is passed to a quick run command

[insin]

$ nwb inferno run NonExistent.js
Starting Webpack compilation...
Failed to compile with 1 error.

 ERROR  in /path/to/nwb/lib/inferno/renderShim.js
Module not found: Error: Can't resolve 'nwb-quick-entry' in '/path/to/nwb/lib/inferno/'

We should probably check if the file exists up-front.

I saw this problem too...

And struggle to resolve this, but I can't get any solution yet.

I think nwb failed to create and init something of a Webpack part at renderShim.js

Installing new npm packages around, it might causes this problem.

$ nwb inferno run NonExistent.js
NonExistent.js does not exist.
