FGS stop log bug fix

Browse Source 
Updating location of log to be before type is cleared. Also restricting
logging to cases where we have a UidState.

Adding in log lines for when there is no API type (since the FGS should
have a type)

Bug: 294585409
Test: manual testing on device along with unit testing
