Importing worlds with name other than 'Bedrock Level' doesn't work

Make sure new servers are not started until all properties are set.

A quick fix is to rename all world files 'Bedrock Level' but in the long run level name should match server name.

Presumably level_name.txt must match the server.properties level-name value.

Also do not rely on the zip name for anything. Assume the zip name has no relation to what is inside the zip.

There may be problems currently with importing any world on run.

Turned out I had removed the code that copies over world files.
