fix(#349: cannot find stage after hot-deploy)

Because hot-deploy creates a new classloader for everything, a new
SmvDataSet object instance is also created, which is different from the
old SmvDataSet object. Therefore we will need to use the SmvDataSet name
to find the owning SmvStage in order to find the published version.
