failure version 0.11 with sockJS

[jamalsoueidan]

Expected Behavior

When I rerun my application the sockJS connection is broken!

Actual Behavior

First time it works, second time it stops working for unknown reason.

Is an error being thrown?

Uncaught SyntaxError: The URL 'http:/localhost:3000' is invalid

@jamalsoueidan Thank you for opening this issue. It looks like the problem was a change to how module resolutions were stored that modified query params changing ?http://localhost:8080 to ?http:/localhost:8080.
