Steps to reproduce

1.  export an entire workspace (within JCR-Tools app)
2.  Add the resulting XML in mgnl-bootstrap-sample
3. This will work fine
4. Now trigger an update, update the mgnl version or so.

-> Exceptions galore.

The 'fullpath' in info.magnolia.importexport.BootstrapUtil will become empty, so it will not remove preexisting nodes.

info.magnolia.module.delta.SamplesBootstrapTask will btw always do ImportUUIDBehavior.IMPORT_UUID_COLLISION_THROW and I dont' see a way to override that.

Btw, I think the name based code BootstrapUtil is error prone too. If e.g. I just make up a name for the XML in mgnl-bootstrap-sample, it will work fine, but will then fail only at an update. Using the name to determin what the path is what is going to be overrwritten seems pleonastic. The path is in the xml/yaml itself isn't it?
