Routing.root_path() is "" when it should be "/"

[glennfu]

In my console:

>> include ActionController::UrlWriter
=> Object
>> root_path
=> "/"

In the javascript console:

>>> Routing.root_path()
""

Changing generate.js.erb to:

while (path[path.length - 1] == "/" && path != "/") {

fixes it. Does that look right?

At a glance, yes, that looks right to me. Pull request?
