test: physical: Cover trigger:none, brigtness:asserted branch

The test causes execution to take the following path in
setInitialState(), previously outlined in 264d909d3dc9 ("test: Add tests
for Physical class") as being missed:

    auto brightness = led.getBrightness();
    if (brightness == ASSERT)
    {
        // LED is in Solid ON
        sdbusplus::xyz::openbmc_project::Led::server ::Physical::state(
            Action::On);
    }

This brings the line coverage to 97.6% (function coverage remains
unchanged by this patch).
