PlatformIO runs the build step for each unit test. This builds only the unit test files as long as the other source files don't change. But setting BUILD_EPOCH to $UNIX_TIME will trigger a full rebuild of the source for each unit test. This also has a side-effect of resetting the incremental coverage data before each test. This PR adds a step to disable adding the BUILD_EPOCH define while running the unit tests.
