Print RF map for roaming tests and fix sensitivity test cases.

This CL adds a logging line in roaming tests to verify RF connection
maps, i.e., the connections between the access point, DUT, and
attenuator. The CL also fixes a bug in generating sensitivity test cases
that was resulting in only the first channel being tested.

Test: Done
Bug: None
