Revert "Revoke 'always' web handler status when not autoverifying"

This reverts commit ce22265eeda3a96613b9a7bb7dd898c69d295964.

Reason for revert: Inadvertently broke link handling stickiness even for well behaved apps

Bug: 146204120
Test: install app that handles web urls; set to 'always' in Settings;
install same apk again.  Verify that app is still in 'always' state via
'adb shell dumpsys package d'
