Fix grouping bar for topologies that don't support grouping

- fixes #61
- dont clear nodes cache if topo is the same
- combined stores that were interdependent
- dont show topology grouping menu if unsupported
- also harmonized some variable names
- removed old grouping switcher
- moved topo actions to app actions, removed search
- get correct topology url
- first JS test using Jest
- make tests run on circle using the build container.
- replaced jest test runner with karma/jasmine
- Use debian for UI build and test container.
- updated karma-browserify
