Adds an angular $urlRouterProvider service Rule to the Core module
configuration, that removes any trailing slashes in the URL for all routes.
The Rule is defined in the core routes configuration. Thus, in order for
this to work on all routes in the application, we have to inject the Core
module into each client module, as a dependecy in the client.module
configuration. Otherwise, we'd have to define the Rule in each module's route
configuration individually.
Adds missing client-side route configuration tests.
Tests demonstrate that the various route configurations can handle a trailing
slash in the URL, and gets resolved to the correct client route.
Fixes#1075
