Fingerprint enrollment dialogue without "Add" button

SUMMARY
When clicking "X" to back out of fingerprint enrollment on the finger selection screen (immediately after clicking "Add"), the next time one opens the dialog it does not have an "Add" button. It is then impossible to enroll a finger without fully closing+reopening the KCM.

STEPS TO REPRODUCE
1. Open systemsettings kcm_users
2. On the user page, click "Configure fingerprint authentication"
3. Press "Add"
4. Do not select a finger, but press "X" to close
5. Click "Configure fingerprint authentication" again

OBSERVED RESULT
The "Add" button at the bottom of the dialogue is missing (see attachment).

EXPECTED RESULT
The "Add" button remains accessible.
