Update description of reset_sensors test

[scpeters]

🦟 Bug fix

Fixes comments describing a test

Summary

I noticed that the INTEGRATION_reset_sensors test is failing in #2232, and while reading through the test I noticed that the test description doesn't seem to match what the test is doing and appears to be copied from test/integration/sensors_system.cc. This updates the comment with my understanding of what the test appears to do.
