The models.Compose.toplevel_dir property returns the latest-odcs-22955-1/ directory if the compose is not failed. If it is failed, it fallbacks to odcs-22955-1-20180919.n.0 directory, because the latest-* directory is created only for non-failed composes..

This is causing problems for PungiLogs class which is looking for Pungi logs to include them in the Compose.state_reason. When The PungiLogs is called, the compose might not be in failed state, because we are calling PungiLogs in the exception handler which will actually move the Compose to that failed state later.

In order to fix that, I've added Compose.toplevel_work_dir which always returns the the odcs-* toplevel directory which is created no matter what the composes state is and where the logs always exist.
