Use correct environment for flush operation

Use the original environment with a slow sensor request rate for the
flush operation in the reconfigure while active tests. Previously, the
new environment that requested a higher ODR was being used which
caused the sensor to be reconfigured too early because the flush
operation immediately registers a sensor listener. This change ensures
that the sensor will not be reconfigured before the flush operation is
executed.

Bug: 132312939
Test: Verified there is a two second delay before sensor is
      reconfigured
Test: Verified test passes
