Get correct hasEnrolled for work profiles

The check within BiometricService is done from system server process
so we need to pass in the actual userId.

Bug: 111461540

Test: With normal profile and FP enrolled, with work profile and no
      FP enrolled, launching BiometricPromptDemo for work profile
      and attempting to start authentication shows "none enrolled" message.
