Always-wide-color should prevent dynamic color

Currently, the tests for always-wide and dynamic-wide are
separate. A bug was found and fixed [1] where the always-wide
support wasn't being checked when dynamic-wide was enabled.

This CL returns false in the dynamic-wide test if always-wide
is enabled.
