[PATCH 15/16] tests: Add a WNM tests to check candidate list is used if not required

[benjamin at sipsolutions.net]

From: Benjamin Berg <benjamin.berg at intel.com>

This tests that the candidate list is used even if it is not required
because the abridged and preferred candidate list included bits are not
set.
