- Added requireAtLeast to ENFVersion

- Throw UnsupportedENFVersionException in provideDiagnosisKeys
- Adjusted Tests

* 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

* 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.

* 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.

* Flush the json data after writing it, otherwise if the app process dies, we end up with an empty file.
GSON deserializes this into a null object that looks like a non-null object until it is evaluated some time later.

Force an evaluation via `require(it.size >= 0)` and delete the corrupt data file when catching the exception.

and overwrite them if necessary (currently only needed for CalculationTrackerStorage.kt).
