* Fix unnecessary refreshes in resultRequests

* satisfy circleCI

* Fix unreliable test.
Random could be randomly 0 which would fail the test.

* Create types for buildflavors to prevent string comparison.
Use these build variants for specific tests.

* Don't assign the times variable to a final value as it breaks tests.
Until refactored, it's okay to recalculate this.

* Remove a few sonar code smells.

* Fix broken instrumentation test for key verification.
Add matching binary, signature and pubkey from pod.

* Fixed test regression due to refactoring.

* Integrate pulling the supportedCountries data from the AppConfig for the submission transaction.
(Previously wasn't implemented yet, now it's merged)

The UI requires the list to be empty, if it is empty in the config.
I've moved the fallback country insertion into the transaction.

Version code bump to 42

Perform data reset for users already affected by the encryption issues (EXPOSUREAPP-1851/EXPOSUREAPP-2958) (#1256)

* A reset mechanism that performs a data reset for those (and just those) already affected by the pre 1.4.0
encryption error. If encountered the preference and database file will be deleted, then we will retry
to generate an EncryptedSharedPreferences instance, and show the user a popup about what happened.

TODO: This still has placeholders for the popup dialog.

Early returns help code readability if used as guard closes.

* Add final texts and fix missing dialog in other build flavors.

* Additional test that we also match nested exceptions.

* Fix incorrect shared preferences path.

* Make klint happy.

* Address PR comments.
