Bug Description

Fingerprint enroll progress is NOT displayed for immediate 2nd fingerprint enrollment with out closing the FP GUI.
2nd finger enrollment: After first swipe of 2nd FP, even though progress is not displayed on circle for 2nd fingerprint, it is properly enrolled after continuous swipe and later it will be identified, but user will have confusion about appearance that is the 2nd finger enrollment is happening or not.

Steps to reproduce:
Enroll 1st FP ==> enrollment progress is shown on circle, after it completes, don't close GUI, proceed with 2nd finger enrollment
Enroll the second FP ==> observe that enrollment progress is NOT shown on circle, but if we keep on placing finger, after few attempts, finger will be enrolled.

verified on two DELL models
model-1: latitude 7300: 2nd fp enrollment progress is shown for 1 or 2 swipes, but didn't completed the progress circle.
model-2: latitude 7520: 2nd fp enrollment progress is NOT shown at all

Both cases 2nd FP enrollment is done and later it is also identified, only progress is NOT displayed.

journlctl --unit fprintd.service was shown the messages of fingerprint enroll swipes properly with out any issues

"Capture initiated, please place your finger now n the sensor now" for all swipes.
