- We need to decouple all frontend services from URL service as much as possible. "bootstrap" module is now a central point to substitute (proxy really) function previously done by the URL service and this move changes direct usage of URL service to "bootstraps" internal proxy function

- By becoming a parameter in the routing bootstrap process URL is Service no longer a "require" inside the frontend controllers but rather becomes a part of the "internal API" of the bootstrapper. This is not the end form of it, rather a step closer to decouplint routing from the URL serivce.
- The bootstrap module needs a facelift to have cleaner distinction between init/start methods. This is left for another time
- this is a small part of a bit of cleanup of our test files
- the goal is to make the existing tests clearer with a view to making it easier to write more tests
- this makes the test structure follow the codebase structure more closely
- eventually we will colocate the frontend tests with the frontend code
