Do not build sample app executable when building unit tests.

Unit tests define an OPENER_ASSERT macro that requires linkage to a function
defined in OpENerTests.cpp, which is not compiled for the sample application.
Unit tests are built into a separate executable, so building the sample is
not required anyway.
