Solr 4.5 collection api ignores collection.configName when used in cloud

This worked properly in 4.4, but on 4.5, specifying collection.configName when creating a collection doesn't work - it gets the default regardless of what has been uploaded into zk. Explicitly linking config name to collection ahead of time with zkcli.sh is a workaround I'm using for the moment, but that did not appear to be necessary with 4.4 unless I was doing something wrong and not realizing it.
