I ran into the exact same situation recently. I unloaded from the browser GUI which does not delete the data or instance dirs, but does delete core.properties. I couldn't find any API either so I eventually manually recreated core.properties and restarted Solr.
Would be nice if the core.properties file were to be renamed rather than deleted and if there were a RESCAN action to scan for unloaded cores and reload them.
