This reverts commit 6b6d8c0d6d.
Reason for revert: Should use shouldFinishWhenBackgrounded() to
control the behavior during onStop()

During BiometricEnrollBase::onStop(), it judeges activity result and
determine finishing self or not by a common rule. And it causes some
problems.
1. It may override original setResult() which was set by its child
activity.
2. If we change the judgmental rule in BiometricEnollBase, we need to
manully test all override class cases to make sure everything works
well. It makes us hard to change the criteria here.
Move code in BiometricEnrollBase::onStop() to its extended class to have
more flexiable.
