SF: Fix unit test getColorModes() expectation

4b0e4ddf4 changed when the composer getColorMdoes() function is called,
so that it is only called if wide color displays are configured as
supported.

This patch simple adjusts the tests so that the call is no longer
expected.

Test: atest libsurfaceflinger_unittest
