bootstrap-loader: Bug in bootstrap v4, alpha 3: cannot find 'bootstrap' in node_modules

Hey,

Not sure if this is something I am doing wrong, but I have been using this loader for months now and noticed that with the latest patch, my bootstrap folder cannot be resolved anymore. I am using bootstrap 4 alpha 2 but now it doesn’t seem to be resolving the folder. When I run debug it goes to

[bootstrap-loader]: Using Bootstrap module: bootstrap. 

and then throws this error:

./~/bootstrap-loader/lib/bootstrap.loader.js!./~/bootstrap-loader/no-op.js
[0] Module build failed: Error: 
[0]       Could not find path to 'bootstrap' module.
[0]       Make sure it's installed in your 'node_modules/' directory.

Any help would be much appreciated!
