banner.py: fix import specification for getBackendURL (#2584)

Browse Source 
* banner.py: fix import specification for getBackendURL

Use the constant Dirs.STATE_PATH

* state.js: only `getBackendURL` dynamically when running client side

During server side rendering, `getBackendURL` cannot access the current
location from the `window`, because there is no `window`.

* Better client-side context checking

Thanks jackie
