FirebasePerformance Log show that our slowFrame&frozenFrame data for each page is added on top of the data for all previous pages，maybe need to call FrameMetricsAggregator.reset method at activity stop lifecycle to solve this problems

Every time the FrameMetricsAggregator.remove method is called, it returns the same mMetrics instance that was not cleared at the stop time, resulting in all pages using the same data
