Ensure that we log the location of the runtime properties file

OpenmrsUtil.getRuntimeProperties() is supposed to log the location of the runtime properties file in use. But by the time this happens, the log level is not yet set with OpenmrsUtil.applyLogLevels(). We need fix this because many times people struggle to know the exact location and name of the runtime properties file that is in use such that they can be able to change some settings to fix an openmrs instance that fails to start.
