* Make key provider unit tests more specific.

* Add time unit to parameter name.

Changed ApplicationConfigurationInvalidException to NormalizedTimePerDayToRiskLevelMappingMissingException

* updated test api fragment to display exposure windows

* do not show dummy text on device

* removed it

- Added requireAtLeast to ENFVersion
- Added UnsupportedENFVersionException
- Throw UnsupportedENFVersionException in provideDiagnosisKeys
- Adjusted Tests

removed useless test

* Show aggregated risk result in testmenu riskCalculationFragment

* Use extention fun to build string for aggregated result

* Show exposure window count and exposure windows as json

+ fixed a layoutbug with cut off

* satisfy lint

* Use real values

* Connected ExposureResultStore

* ENF v2 Calculation adjusted Testmenu Entry for v2

* Adjusted to ExposureResultStore changes

* Added logs

* Removed and adjusted some old stuff

* Made backend parameters a little bit better readable

* its better this way

* Created additional risk calc info

* Refactoring

* sourcecheck clean

* do not prematurely abort diagnosis keys task, if there is no last server fetch time; before anything else store time stamp after successfully submitting keys to enf

* comments and logs

* We need to reset the tracked exposure detections on app reset.

* Make sure that all flow preferences reset when we use the app reset function.

* Add workaround for EncryptedSharedPreferences, it's `clear` behavior is not like a normal sharedpreference,
as no listeners are called when keys are removed.

* Fix failing test.
