[Wifi connected score] Update values after reset

The filtered rssi and rate of change were not getting updated the
first time after a reset. Mostly this affected values logged by
WifiScoreReport in dumpsys output, but an effect on adjustThreshold()
behavior was possible.

Bug: 69415543
Test: Unit tests
Test: adb shell dumpsys wifi WifiScoreReport, check filtered_rssi column
      for first row of each session.
