Test the JLog::setInstance method to make sure that if we set a logger instance JLog is actually going to use it. We accomplish this by setting an instance of JLogInspector and then performing some operations using JLog::addLogger() to alter the state of the internal instance. We then check that the JLogInspector instance we created (and set) has the same values we would expect for lookup and configuration so we can assert that the operations we performed using JLog::addLogger() were actually performed on our instance of JLogInspector that was set.
