Cause: with unified screenlock, ConfirmDeviceCredentialActivity didn't
forward result with FLAG_ACTIVITY_FORWARD_RESULT
Also, fixed that ConfirmDeviceCredentialActivity didn't allow fingerprint
authenication in unified screenlock after keystore unlocked.
In ChooseLockSettingsHelper, add one new util function to allow
extra option to set returnCredentials to false while external to true.
Set StrongAuth to "not required" when it has been successfully unlocked.
Test:
1. PO Unified Screenlock/Work Challenge x fingerprint -> ok to trust cert
(Also, no credential is returned in intent)
2. WorkMode off -> Reboot -> turn on Work mode
-> no fingerprint option, PIN unlock successful to turn work mode on

1. Split existing tests into fully automatable (unit/) and not fully
automatable (app/)
2. Revert previous changes to test runners on app/
3. Fix some typos in readme
This will enable us to add the fully automatable test target
SettingsUnitTests to the continuous integration tests on the platform.
