Fixed Exception when relocating EnderIO BlockEntity

[Alexander3a]

The chunk relocation process fails when a chunk contains any EnderIO BlockEntity due to the way these entities save their content. The format used by EnderIO BlockEntities is currently not handled by the relocator. However, since these BlockEntities do not contain any data that requires relocation (as far as I know), it should be safe to skip over them during the relocation process.
