Login dialog shows error for Safari with Private Window mode (#1172)

* #958 new StorageService service

abstraction around ‘Storage’ to allow switching to in-memory store
whenever ‘localStorage’ is not available (i.e. private/incognito modes,
etc.)

* fix unit tests

* update unit tests

- disable incorrect auth tests (core)
- simplify widget visibility tests (activiti-form)

* fix unit tests
