Release version 1.6.1

Cannot delete tests older than 21 days - DE: Tests die älter als 21 Tage sind, können nicht gelöscht werden (EXPOSUREAPP-2398) (#1586)

* 1. Replaced redundant uiStateState during test result fetch with a NetworkRequestWrapper that is able to represent multiple states. This allows for better request state handling throughout the app
2. Completely removed the SubmissionViewModel
3. Failure to fetch the test should now always display the invalid test card on the home screen

* Keep displaying fetching card on server errors as this usually does not indicate any problems with the test itself

Signed-off-by: Kolya Opahle <k.opahle@sap.com>

* Fixing unit tests (mostly just syntax, one test case changed due to new card)

Signed-off-by: Kolya Opahle <k.opahle@sap.com>

* Promoted unknown host exception to server exception

* Make config sharing behavior `SharingStarted.Lazily`. (start once, never release)
Otherwise classes that are just interested in the current config, if there is no other subscriber active,
would launch the `startValueProvider` and pull a config each time.

The ExposureDetectionTracker is such a candidate that would like to use the latest config every ~3min.

While this already no longer happens since "Track config changes" (4d1ecb54),
because there is no a class that is permanently subscribed to `currentConfig`, we should not rely on side-effects,
so let's make the sharing behavior explicit.

* Fix test regression.
