Adjust defaults for ExtractCommand

It now extracts the contents of the JAR in a folder named after the JAR
without the extension. It now also checks if the folder is empty.
There's a new --force option to skip those checks.

The "runner.jar" is now named like the uber JAR from which the
extraction has been started.

See gh-38276
